Step 2021

以下有几个部分：
ROLE_AND_TASK：你的角色定义以及任务描述
TOOLS：你可以调用的工具列表，以及每个工具的参数说明
OUTPUT：输出相关规则和约束
TIPS：重要建议
SITUATION：操作历史和任务相关状态

<ROLE_AND_TASK>
你是一个计算机操作代理，正在操作 Ubuntu Linux 桌面。你可以通过截图查看屏幕，并使用鼠标和键盘动作来控制它。

你的任务是：借助工具，来操作一台电脑来达成任务: Create a new sheet named "Sheet2" and merge cells A1:C1 to write the header "Investment Summary". Beneath that, merge cells A2:B2 to write "High Interest Rate" and merge cells C2:D2 to form "Low Interest Rate".。
电脑的操作系统: Ubuntu Linux

工作流程：
1. 理解当前的情况（SITUATION），SITUATION 中会包括策略树状态、任务失败条件列表、关键视觉证据、上次返回的操作、屏幕截图（上次操作前 & 上次操作后）、历史操作简述。
2. 思考如何尽快达成任务，规划接下来的动作。可以是1次动作，也可以是一组BATCH动作。BATCH动作原则见下。
3. 输出tool_calls：包含你规划的需要执行的电脑操作以及维护 SITUAION 的工具调用。
4. 重复上面步骤，直到任务达成。

关于策略树：
- 策略树是一个分层的任务管理结构。
- 它可以帮助你组织和跟踪任务所需的步骤。也可以帮助你在某个细分尝试方向失败时，回退到高级的节点来尝试其他方法。通过维护策略树，你可以系统地分解复杂任务，并且在较困难的子任务中大胆尝试，确保每一步都得到适当的关注和执行。
- 策略树必须以层次结构组织，实例：
`1`: 顶层任务。重要目标或里程碑，从用户给出的任务开始拆解。
`1.1`, `1.2`, ...: 任务 `1` 的子任务。
`1.1.1`, `1.1.2`, ...: 任务 `1.1` 的子任务或尝试路径方案。它们不是实际动作，而是对父任务的子目标贡献。

关于失败条件列表：
- 失败条件列表是一个 checklist
- 它用于辨认当前任务是否还有达成的可能。当所有失败条件都被确认为真后，任务将返回不可能达成。

关于关键视觉证据：
- 关键视觉证据是一些屏幕状态的描述，这些状态可以通过截图来验证。
- 任务完成后，验证模块会检查这些视觉证据是否都满足，以判断任务是否成功完成。

</ROLE_AND_TASK>

<TOOLS>
你拥有以下工具：computer、update_strategy_tree。
每次调用必须包含computer工具的调用来执行电脑操作，update_strategy_tree工具的调用则根据需要选择性使用来维护策略树状态。

## computer
操作电脑的动作库，调用它以在桌面上执行操作。

坐标值定义：
在最新一张屏幕截图中的坐标轴比例，使用 [0, 1] 范围内的归一化值。其中 (0, 0) = 屏幕左上角，(1, 1) = 屏幕右下角。

操作和参数说明：
1. 移动鼠标
{
  "action": "mouse_move",
  "to_coordinate": [float, float], # 移动到的坐标值。
}

2. 移动鼠标并点击鼠标按键
{
  "action": str, # 鼠标按键操作，one of left_click | right_click | middle_click | double_click | triple_click
  "at_coordinate": [float, float], # 移动到的坐标值。
  "with_key": str or None, # 点击时按住的键盘按键(比如"ctrl"、"shift")，如没有则填None。
}

3. 按住鼠标左键并拖动
{
  "action": "left_click_drag",
  "from_coordinate": [float, float], # 起始到的坐标值,
  "to_coordinate": [float, float], # 移动到的坐标值。
  "with_key": str or None, # 点击时按住的键盘按键(比如"ctrl"、"shift")，如没有则填None。
}

4. 输入文字
{
  "action": "type",
  "text": str, # 要输入的文字
  "submit": bool, # 输入后是否按 Enter 键提交
}

5. 键盘按键（单个或组合键）
{
  "action": "key",
  "text": list[str], # 要按的键盘按键组合(如"enter"、"tab"、"ctrl"),
  "with_duration": float or None, # 按键持续时间（秒），如点击则填 null。
}

6. 移动鼠标并滚动鼠标滚轮
{
  "action": "scroll",
  "at_coordinate": [float, float], # 滚动位置的坐标值
  "scroll_direction": str, # 滚动方向，one of "up" | "down" | "left" | "right"
  "scroll_amount": int, # 滚动量，1-30，模拟人类滚轮滚动的幅度。较大的值表示更大幅度的滚动。
}

7. 等待
{
  "action": "wait",
  "duration": float, # 等待秒数。根据操作后界面变化的复杂程度调整等待时间。
}


BATCH动作原则：
BATCH动作指一组连续且相对固定的电脑操作，主要用来减少不必要的对话过程。
- 例如：顺序输入（type→Tab→type）、键盘快捷键（Ctrl+C 然后 Ctrl+V）、输入一段字符后 Enter（在搜索输入框中常用）。
- DO NOT BATCH：涉及界面状态变化等待的操作（如打开菜单/对话框后等待动画）→ 依赖新坐标的操作。例如：点击打开一个菜单后，等待菜单完全展开再点击菜单项，因为菜单项的坐标在菜单完全展开前可能不稳定；滚动页面后再点击某个元素，因为滚动会改变元素的坐标。
**只在比较确定的操作中可以使用多个动作组合。当你不确定时，使用单个动作是更保险的做法**

## update_strategy_tree
维护策略树的相关工具

1. 创建新任务节点
{
  "action": "create",
  "parent_id": str or None, # 父任务ID，根任务则填None。此操作会在这个父节点下顺序创建子节点。
  "description": str, # 任务描述
}

2. 更改节点状态
{
  "action": "change_status",
  "id": str, # 任务ID，使用点号分隔的层次编号（如 1.2.1），程序会自动解析层级关系。
  "new_status": str, # 新状态，one of None | "success" | "fail"
  "fail_reason": str or None, # 失败原因，仅在 new_status=fail 时需要提供
}
</TOOLS>

<OUTPUT>
你需要调用工具来规划接下来需要执行的电脑操作，以及维护SITUATION（如果需要）。
另外你需要输出从最新的屏幕截图中观察到的重要信息、你对当前情况的分析、为什么这么做的思考过程（thoughts）。

</OUTPUT>

<TIPS>
- 尽量以最少的操作数完成任务。每个动作都应该有明确的目的，并直接推动任务向前发展。
- 优先操作成功率，其次是操作的效率。
- 尽可能使用键盘快捷键（例如 ctrl+l 聚焦浏览器地址栏），以增加操作的成功率。
- 如果一段时间的多个动作后还未产生预期结果，参考策略树中其父节点的目标并尝试替代路径。
- 始终记得完成时保存文件（例如 ctrl+s），除非任务明确说不需要。
- 永远不要假设操作成功。寻找预期变化的具体视觉证据。
- 如果截图与上一张相同，说明上一次操作没有产生任何效果。不要假设它成功——诊断为什么失败并尝试不同的方法。
</TIPS>

- File is read-only and cannot be modified
- Permission denied to create new sheets in the workbook

## 3. 关键视觉证据
- Sheet2 tab is visible and active at the bottom of the screen
- Row 1 shows merged cells A1:C1 containing the text 'Investment Summary'
- Row 2 shows merged cells A2:B2 containing the text 'High Interest Rate'
- Row 2 shows merged cells C2:D2 containing the text 'Low Interest Rate'

## 4. 上一次返回的决策

### 4.1. 上一次的观察和思考
```
#### 重要信息

- Sheet2 is active and "Investment Summary" has been successfully entered in the merged cell A1:C1
- The text "Investment Summary" is visible in row 1, spanning columns A through C
- The cell reference box shows "A1:C1" confirming the merge
- Row 2 is empty and ready for the next headers
- Need to select cells A2:B2, merge them, and type "High Interest Rate"
- Then select cells C2:D2, merge them, and type "Low Interest Rate"

#### 情况分析与思考过程

Great progress! The first header "Investment Summary" is now in place in the merged cell A1:C1. Now I need to:

1. Select cells A2:B2 by clicking and dragging from A2 to B2
2. Merge these cells
3. Type "High Interest Rate"
4. Then select C2:D2, merge them, and type "Low Interest Rate"

Let me start by clicking on cell A2 and dragging to B2 to select the range A2:B2. I'll update the strategy tree to mark task 2 as success and start working on task 3.
```

### 4.2. 上一次返回的操作
{"function": {"name": "computer", "arguments": {"actions": [{"action": "left_click_drag", "from_coordinate": [0.078, 0.304], "to_coordinate": [0.121, 0.304]}]}}}

## 5. 屏幕截图

### 步骤 1:
- 描述:
  ```
  #### 重要信息
  
  - LibreOffice Calc is open with file "FutureValue.xlsx"
  - Currently on Sheet1 which contains investment data (Present Value, Years, Annual Interest Rate, etc.)
  - Sheet1 tab is visible at the bottom left of the screen
  - Need to create Sheet2 and set up merged cells with specific headers
  
  #### 情况分析与思考过程
  
  The task requires me to:
  1. Create a new sheet named "Sheet2"
  2. Merge cells A1:C1 and type "Investment Summary"
  3. Merge cells A2:B2 and type "High Interest Rate"
  4. Merge cells C2:D2 and type "Low Interest Rate"
  
  To start, I need to right-click on the sheet tab area (where "Sheet1" is shown) to bring up the context menu that will allow me to insert a new sheet. The Sheet1 tab is located at the bottom left of the screen.
  
  I'll first create the strategy tree structure, then execute the right-click action on the sheet tab.
  ```

  - "New sheet" option is selected
  - The Name field already contains "Sheet2" (perfect!)
  - "Before current sheet" position is selected
  - The OK button is visible at the bottom right of the dialog
  
  #### 情况分析与思考过程
  
  The dialog is already configured correctly with the name "Sheet2". I just need to click the "OK" button to create the new sheet. After creating the sheet, I'll need to:
  1. Select and merge cells A1:C1, type "Investment Summary"
  2. Select and merge cells A2:B2, type "High Interest Rate"  
  3. Select and merge cells C2:D2, type "Low Interest Rate"
  
  Let me click OK to proceed with creating Sheet2.
  ```

### 步骤 4:
- 描述:
  ```
  #### 重要信息
  
  - Sheet2 has been successfully created and is now active
  - The sheet is empty with cell A1 currently selected
  - I can see the Sheet2 tab is highlighted at the bottom, showing "Sheet 1 of 2"
  - Now I need to set up the merged cells with headers as specified
  
  #### 情况分析与思考过程
  
  Great progress! Sheet2 is now created and active. Next steps:
  1. Select cells A1:C1, merge them, and type "Investment Summary"
  2. Select cells A2:B2, merge them, and type "High Interest Rate"
  3. Select cells C2:D2, merge them, and type "Low Interest Rate"
  
  To select A1:C1, I'll click on cell A1 and drag to C1. Since A1 is already selected, I can drag from A1 to C1 to select the range.
  
  Let me first update the strategy tree to mark task 1.5 as success, then proceed with selecting and merging cells A1:C1.
  ```
  
  I'll update the strategy tree to reflect the successful creation of Sheet2, then select cells A1:C1 by clicking and dragging from A1 to C1.
- 操作:
  1. 按住鼠标左键从坐标 (0.078, 0.287) 拖动到坐标 (0.164, 0.287)

### 步骤 5:
- 描述:
  ```
  #### 重要信息
  
  - Cells A1:C1 are successfully selected (shown in blue highlight)
  - The name box shows "A1:C1" confirming the selection
  - Status bar shows "Selected: 3 rows, 3 columns"
  - Sheet2 is active and ready for the next operations
  
  #### 情况分析与思考过程
  
  Perfect! I've successfully selected cells A1:C1. Now I need to:
  1. Merge these cells
  2. Type "Investment Summary"
  
  To merge cells in LibreOffice Calc, I can use the Format menu. I'll click on Format menu and look for the merge cells option. After merging, I'll type the header text.
  
  Let me update the strategy tree to mark task 2.1 as success, then proceed to merge the cells via the Format menu.
  ```
- 操作:
  1. 左键单击坐标 (0.15, 0.069)

### 步骤 6:
- 描述:
  ```
  #### 重要信息
  
  - Format menu is now open
  - "Merge and Unmerge Cells" option is visible in the menu
  - Cells A1:C1 are still selected (shown in the background spreadsheet)
  - The menu shows various formatting options
  
  #### 情况分析与思考过程
  
  The Format menu has opened successfully. I can see "Merge and Unmerge Cells" option in the menu. I need to click on it to access the merge cells functionality. This should either directly merge the cells or show a submenu with merge options.
  
  After clicking on "Merge and Unmerge Cells", I expect to see merge options. Once the cells are merged, I'll type "Investment Summary" in the merged cell.
  
  Let me click on "Merge and Unmerge Cells" to proceed.
  ```
- 操作:
  1. 左键单击坐标 (0.193, 0.278)

### 步骤 7:
- 描述:
  ```
  #### 重要信息
  
  - The Format menu is open with a submenu showing merge options
  - Three options are visible: "Merge and Center Cells", "Merge Cells", and "Unmerge Cells"
  - Cells A1:C1 are still selected (shown in the background)
  - I need to click on "Merge Cells" to merge the selected range
  
  #### 情况分析与思考过程
  
  The previous action successfully opened the merge submenu. Now I need to click on "Merge Cells" to merge the selected A1:C1 range. This will combine the three cells into one merged cell.
  
  After merging, I'll type "Investment Summary" in the merged cell, then proceed to:
  1. Select and merge A2:B2, type "High Interest Rate"
  2. Select and merge C2:D2, type "Low Interest Rate"
  
  Let me click on "Merge Cells" option.
  ```
- 操作:
  1. 左键单击坐标 (0.326, 0.298)

### 步骤 8:
- 描述:
  ```
  #### 重要信息
  
  - Cells A1:C1 are still selected (shown in orange highlight)
  - The cell reference box shows "A1:C1" indicating the cells are not yet merged
  - The Format menu has closed from the previous action
  - The merge operation did not complete successfully
  - I need to reopen the Format menu and try the merge operation again
  
  #### 情况分析与思考过程
  
  The previous attempt to click on "Merge Cells" from the submenu didn't work - the cells are still separate. I need to:
  1. Reopen the Format menu
  2. Click on "Merge and Unmerge Cells"
  3. Select the appropriate merge option
  
  Since A1:C1 is still selected, I can proceed directly to opening the Format menu again. Let me click on Format in the menu bar.
  ```
- 操作:
  1. 左键单击坐标 (0.15, 0.069)

### 步骤 9:
- 描述:
  ```
  #### 重要信息
  
  - The Format menu is currently open
  - I can see "Merge and Unmerge Cells" option in the menu with an arrow indicating a submenu
  - Cells A1:C1 are still selected (highlighted in orange/blue)
  - The cell reference box still shows "A1:C1" indicating the cells haven't been merged yet
  - The previous attempt to click on "Merge Cells" didn't work - the menu is still open
  
  #### 情况分析与思考过程
  
  The previous click didn't successfully activate the merge function. Looking at the Format menu, I can see "Merge and Unmerge Cells" option which should have a submenu. I need to click on "Merge and Unmerge Cells" to expand its submenu and then select the appropriate merge option.
  
  The coordinates in the previous attempt (0.326, 0.298) might not have been accurate. Looking at the current menu, "Merge and Unmerge Cells" appears to be around y-coordinate 0.278 or so. Let me click on "Merge and Unmerge Cells" to open its submenu.
  
  After successfully merging A1:C1, I'll:
  1. Type "Investment Summary" in the merged cell
  2. Select and merge A2:B2, type "High Interest Rate"
  3. Select and merge C2:D2, type "Low Interest Rate"
  ```
- 操作:
  1. 左键单击坐标 (0.193, 0.278)

### 步骤 10:
- 描述:
  ```
  #### 重要信息
  
  - The Format menu is open with the "Merge and Unmerge Cells" submenu expanded
  - Three options are visible: "Merge and Center Cells" (checked), "Merge Cells", and "Unmerge Cells"
  - Cells A1:C1 are still selected (highlighted in orange/blue in the background)
  - The cell reference box shows "A1:C1" indicating cells are not yet merged
  
  #### 情况分析与思考过程
  
  The submenu is now open showing the merge options. I need to click on "Merge Cells" (the middle option) to merge the selected A1:C1 range. This should combine the three cells into one merged cell.
  
  After successfully merging:
  1. Type "Investment Summary" in the merged cell
  2. Select and merge A2:B2, type "High Interest Rate"
  3. Select and merge C2:D2, type "Low Interest Rate"
  
  Let me click on "Merge Cells" option in the submenu.
  ```
- 操作:
  1. 左键单击坐标 (0.326, 0.298)

### 步骤 11:
- 描述:
  ```
  #### 重要信息
  
  - The Format menu is open with the "Merge and Unmerge Cells" submenu expanded
  - Three options are visible: "Merge and Center Cells" (checked), "Merge Cells", and "Unmerge Cells"
  - Cells A1:C1 are still selected (highlighted in orange/blue in the background)
  - The cell reference box shows "A1:C1" indicating cells are not yet merged
  
  #### 情况分析与思考过程
  
  The submenu is now open showing the merge options. I need to click on "Merge Cells" (the middle option) to merge the selected A1:C1 range. This should combine the three cells into one merged cell.
  
  After successfully merging:
  1. Type "Investment Summary" in the merged cell
  2. Select and merge A2:B2, type "High Interest Rate"
  3. Select and merge C2:D2, type "Low Interest Rate"
  
  Let me click on "Merge Cells" option in the submenu.
  ```
- 操作:
  1. 左键单击坐标 (0.326, 0.298)

### 步骤 12:
- 描述:
  ```
  #### 重要信息
  
  - The Format menu is open with the "Merge and Unmerge Cells" submenu expanded
  - Three options are visible: "Merge and Center Cells" (checked), "Merge Cells", and "Unmerge Cells"
  - Cells A1:C1 are still selected (highlighted in orange/blue in the background)
  - The cell reference box shows "A1:C1" indicating cells are not yet merged
  - The previous click on "Merge Cells" didn't seem to work as the menu is still open
  
  #### 情况分析与思考过程
  
  The previous attempt to click on "Merge Cells" at coordinates (0.326, 0.298) didn't successfully merge the cells. The menu is still open and the cells remain unmerged. I need to try clicking on "Merge Cells" again, possibly with slightly adjusted coordinates.
  
  Looking at the submenu, "Merge Cells" is the middle option. I should click directly on that text. After the cells are successfully merged:
  1. Type "Investment Summary" in the merged cell
  2. Select and merge A2:B2, type "High Interest Rate"
  3. Select and merge C2:D2, type "Low Interest Rate"
  
  Let me try clicking on "Merge Cells" again with adjusted coordinates.
  ```
- 操作:
  1. 左键单击坐标 (0.326, 0.303)

### 步骤 13:
- 描述:
  ```
  #### 重要信息
  
  - The Format menu is still open with the "Merge and Unmerge Cells" submenu expanded
  - Three options are visible: "Merge and Center Cells" (checked), "Merge Cells", and "Unmerge Cells"
  - Cells A1:C1 are still selected (highlighted in orange/blue in the background)
  - The cell reference box still shows "A1:C1" indicating cells are not yet merged
  - The previous click at (0.326, 0.303) didn't successfully trigger the merge action
  
  #### 情况分析与思考过程
  
  The merge operation still hasn't completed. The menu is open and showing the options, but my clicks aren't registering on the "Merge Cells" option. Let me try a different approach:
  
  1. I could try clicking more precisely on the "Merge Cells" text
  2. Or I could close this menu and try using the merge button in the toolbar if available
  3. Or I could try using a keyboard shortcut
  
  Looking at the submenu, I need to click directly on "Merge Cells". The text appears to be positioned slightly differently than my previous attempts. Let me try clicking at coordinates that would be more centered on the "Merge Cells" text itself.
  
  After the merge is successful:
  1. Type "Investment Summary" in the merged cell
  2. Select and merge A2:B2, type "High Interest Rate"
  3. Select and merge C2:D2, type "Low Interest Rate"
  
  Let me try clicking on "Merge Cells" one more time with adjusted coordinates.
  ```
- 操作:
  1. 左键单击坐标 (0.326, 0.303)

### 步骤 14:
- 描述:
  ```
  #### 重要信息
  
  - The Format menu is still open with the "Merge and Unmerge Cells" submenu expanded
  - Three options are visible: "Merge and Center Cells" (checked), "Merge Cells", and "Unmerge Cells"
  - Cells A1:C1 are still selected (highlighted in orange/blue in the background)
  - The cell reference box still shows "A1:C1" indicating cells are not yet merged
  - Multiple attempts to click on "Merge Cells" from the submenu have not worked
  
  #### 情况分析与思考过程
  
  The menu-based approach isn't working - my clicks on "Merge Cells" aren't registering. I should try a different strategy:
  
  1. Close the current menu by pressing Escape
  2. Look for a merge cells button in the toolbar (there's usually a merge icon in LibreOffice Calc)
  3. Or try using the Format menu again but look for a different approach
  
  Let me press Escape to close this menu first, then I'll look for alternative ways to merge the cells. The toolbar might have a merge cells button that's more reliable.
  
  After closing the menu, I can:
  1. Look for a merge cells button/icon in the toolbar
  2. Or try right-clicking on the selected cells to see if there's a merge option in the context menu
  3. Or try the Format menu again with a different approach
  ```
- 操作:
  1. 按下键盘按键: esc

### 步骤 15:
- 描述:
  ```
  #### 重要信息
  
  - The Format menu has been closed successfully after pressing Escape
  - Cells A1:C1 are still selected (shown in cell reference box "A1:C1")
  - Status bar shows "Selected: 1 rows, 3 columns"
  - Sheet2 is active and ready for the next operation
  - The cells have not been merged yet
  
  #### 情况分析与思考过程
  
  The menu-based approach through Format > Merge and Unmerge Cells wasn't working - my clicks weren't registering on the submenu items. Now that the menu is closed, I should try a different approach:
  
  1. Right-click on the selected cells A1:C1 to see if there's a merge option in the context menu
  2. Or look for a merge cells button in the toolbar
  
  Right-clicking on the selected cells is often a more reliable way to access cell formatting options in spreadsheet applications. The context menu typically provides direct access to merge cells functionality.
  
  After successfully merging:
  1. Type "Investment Summary" in the merged cell
  2. Select and merge A2:B2, type "High Interest Rate"
  3. Select and merge C2:D2, type "Low Interest Rate"
  
  Let me right-click on the selected cells to bring up the context menu.
  ```
- 操作:
  1. 右键单击坐标 (0.121, 0.287)

### 步骤 16:
- 描述:
  ```
  #### 重要信息
  
  - A context menu has appeared after right-clicking on the selected cells A1:C1
  - The context menu shows several options including "Merge Cells" (visible in the menu)
  - Cells A1:C1 are still selected (shown in the background)
  - Sheet2 is active and ready for the merge operation
  
  #### 情况分析与思考过程
  
  The right-click approach worked! The context menu is now showing and I can see "Merge Cells" as an option. This is much more reliable than the Format menu approach I was trying earlier.
  
  Now I need to:
  1. Click on "Merge Cells" in the context menu to merge A1:C1
  2. Type "Investment Summary" in the merged cell
  3. Select and merge A2:B2, type "High Interest Rate"
  4. Select and merge C2:D2, type "Low Interest Rate"
  
  Let me click on "Merge Cells" in the context menu to proceed with merging the selected cells.
  ```
- 操作:
  1. 左键单击坐标 (0.161, 0.44)

### 步骤 17:
- 描述:
  ```
  #### 重要信息
  
  - The context menu has closed after the previous click
  - Cells A1:C1 are still selected (shown in orange highlight and cell reference box shows "A1:C1")
  - The cells have NOT been merged yet - they still appear as separate cells
  - Status bar shows "Selected: 1 rows, 3 columns"
  - Sheet2 is active and ready for the next operation
  
  #### 情况分析与思考过程
  
  The previous click on the context menu didn't successfully merge the cells. The menu closed but the merge operation didn't complete. I need to try again.
  
  Since the cells A1:C1 are still selected, I can try right-clicking again to bring up the context menu and then carefully select the "Merge Cells" option. This approach worked before to bring up the menu, so I should try again with more precise clicking.
  
  After successfully merging:
  1. Type "Investment Summary" in the merged cell
  2. Select and merge A2:B2, type "High Interest Rate"
  3. Select and merge C2:D2, type "Low Interest Rate"
  
  Let me right-click on the selected cells again to bring up the context menu.

  #### 情况分析与思考过程
  
  The right-click successfully brought up the context menu. I can see "Merge Cells" as one of the options in the menu. I need to click on it to merge the selected cells A1:C1.
  
  After successfully merging:
  1. Type "Investment Summary" in the merged cell
  2. Select and merge A2:B2, type "High Interest Rate"
  3. Select and merge C2:D2, type "Low Interest Rate"

  ```
  #### 重要信息
  
  - LibreOffice Calc is open with Sheet2 active
  - Cells A1:C1 are still selected (shown in orange highlight and cell reference box shows "A1:C1")
  - The cells have NOT been merged yet - they still appear as three separate cells
  - Status bar shows "Selected: 1 rows, 3 columns"
  - No context menu is currently visible
  - The previous attempts to merge via context menu and Format menu have not worked
  
  #### 情况分析与思考过程
  
  The cells A1:C1 are still selected but not merged. Previous attempts to click on "Merge Cells" from the context menu haven't been successful. I need to try again with a right-click to bring up the context menu.
  
  Looking at the current state:
  1. Cells A1:C1 are selected and ready to be merged
  2. I need to right-click on the selection to bring up the context menu
  3. Then click on "Merge Cells" option
  
  After successfully merging:
  1. Type "Investment Summary" in the merged cell
  2. Select and merge A2:B2, type "High Interest Rate"
  3. Select and merge C2:D2, type "Low Interest Rate"
  
  Let me right-click on the selected cells to bring up the context menu again.
  ```
- 操作:
  1. 右键单击坐标 (0.121, 0.287)

### 步骤 20:
- 描述:
  ```
  #### 重要信息
  
  - A context menu is open after right-clicking on cells A1:C1
  - The menu shows "Unmerge Cells" option (not "Merge Cells")
  - This indicates that cells A1:C1 are ALREADY merged!
  - The cell reference box shows "A1:C1" 
  - Sheet2 is active and ready for text input
  
  #### 情况分析与思考过程
  
  Excellent! The cells A1:C1 are already merged! The presence of "Unmerge Cells" in the context menu instead of "Merge Cells" confirms that the merge operation was successful in a previous attempt. The cells are now merged and ready for text input.
  
  Now I need to:
  1. Close this context menu
  2. Type "Investment Summary" in the merged cell A1:C1
  3. Then select and merge A2:B2, type "High Interest Rate"
  4. Then select and merge C2:D2, type "Low Interest Rate"
  
  Let me close the menu first by clicking elsewhere or pressing Escape, then type the header text.
  ```
