Step 4018

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: Given a partial calendar, please highlight all the weekends (Satureday & Sunday) by setting the cell background as red (#ff0000). Finish the work and don't touch irrelevant regions, even if they are blank.。
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>

- Non-weekend weekday cells in columns B-F retain their original background color (not red)
- Columns A and G onwards remain unchanged with no red background applied

## 4. 上一次返回的决策

### 4.1. 上一次的观察和思考
```
#### 重要信息

Cell B14 is now selected and shows "12/06/2022" (June 12, 2022 - Sunday) in the formula bar. The status bar shows "Selected: 4 rows, 1 column" which means I have 4 cells selected (B6, B7, B13, and B14).

Current June weekend selection:
- B6 (6/4 - Saturday) ✓
- B7 (6/5 - Sunday) ✓
- B13 (6/11 - Saturday) ✓
- B14 (6/12 - Sunday) ✓

Remaining June weekend cells to select:
- B19 (6/18 - Saturday)
- B20 (6/19 - Sunday)
- B25 (6/25 - Saturday)
- B26 (6/26 - Sunday)

#### 情况分析与思考过程

I need to continue selecting the remaining June weekend cells using Ctrl+click. Looking at the visible calendar, I can see row 15 contains 6/13/2022. Row 19 should contain 6/18/2022 (Saturday). I'll continue adding B19 to the selection.

After selecting all June weekend cells, I'll apply red background color (#ff0000) to them, then repeat the process for July, August, September, and October.
```

## 6. 上一次操作的前50步操作简述
### 步骤 1:
- 描述:
  ```
  #### 重要信息
  
  LibreOffice Calc is open with a calendar spreadsheet showing dates from June to October 2022. The calendar is organized with:
  - Column B: June 2022 (dates visible: 6/1/2022 through 6/30/2022)
  - Column C: July 2022 (dates visible: 7/1/2022 through 7/31/2022)
  - Column D: August 2022 (dates visible: 8/1/2022 through 8/31/2022)
  - Column E: September 2022 (dates visible: 9/1/2022 through 9/30/2022)
  - Column F: October 2022 (currently showing "###" because column is too narrow)
  
  No weekend cells have been highlighted yet. Column F needs to be widened first to reveal the October dates.
  
  #### 情况分析与思考过程
  
  The task requires highlighting all weekend days (Saturday and Sunday) with red background color (#ff0000) across all five months. 
  
  Current progress:
  1. The calendar file is already open in LibreOffice Calc ✓
  2. Column F needs to be widened to see October dates (currently showing "###")
  3. Then I need to identify and select weekend cells for each month
  4. Apply red background color to those cells
  
  First step: Widen column F by dragging the column border between F and G. I'll position on the border line in the header area and drag to the right to reveal the October dates.
  
  I'll also update the strategy tree to reflect the current state.
  ```
- 操作:
  1. 按住鼠标左键从坐标 (0.334, 0.27) 拖动到坐标 (0.38, 0.27)

### 步骤 2:
- 描述:
  ```
  #### 重要信息
  
  LibreOffice Calc is open with the calendar spreadsheet. The previous attempt to widen column F by dragging didn't fully succeed - column F still shows "###" for October dates. The status bar shows "Selected: 1,048,576 rows, 2 columns" which indicates columns F and G are selected rather than just resizing column F.
  
  I can see:
  - Column B: June 2022 (dates visible)
  - Column C: July 2022 (dates visible)
  - Column D: August 2022 (dates visible)
  - Column E: September 2022 (dates visible)
  - Column F: October 2022 (still showing "###" for most rows)
  
  #### 情况分析与思考过程
  
  The previous drag operation selected columns F and G instead of properly resizing column F. I need to:
  1. First, properly widen column F to reveal October dates
  2. Then identify all weekend dates across all 5 months
  3. Select and format each weekend cell with red background (#ff0000)
  
  For widening column F, I should position the cursor precisely on the border line between column F and G headers (the vertical line separating the F and G header cells) and drag it to the right. Let me try a more precise drag operation.
  
  Looking at the header row, I can see the column letters. The border between F and G should be around x=0.384. I'll drag it further right to around x=0.45 to ensure the dates are fully visible.
  ```
- 操作:
  1. 按住鼠标左键从坐标 (0.384, 0.269) 拖动到坐标 (0.45, 0.269)

### 步骤 3:
- 描述:
  ```
  #### 重要信息
  
  The previous drag operation selected columns F, G, and H instead of resizing column F. The status bar shows "Selected: 1,048,576 rows, 3 columns" and these columns are highlighted in orange. Column F still shows "###" for October dates.
  
  I can see the calendar structure:
  - Column B: June 2022 (dates visible)
  - Column C: July 2022 (dates visible)  
  - Column D: August 2022 (dates visible)
  - Column E: September 2022 (dates visible)
  - Column F: October 2022 (still showing "###")
  
  #### 情况分析与思考过程
  
  The drag approach isn't working well - it's selecting multiple columns instead of resizing. Let me try a different approach:
  1. First, click somewhere neutral to deselect the current selection
  2. Then click on the column F header to select just column F
  3. Then I can resize it properly by dragging the border between F and G headers
  
  Let me start by clicking on a neutral area to clear the current selection, then select column F properly.
  ```
- 操作:
  1. 左键单击坐标 (0.312, 0.269)

### 步骤 4:
- 描述:
  ```
  #### 重要信息
  
  The previous click successfully deselected the multiple columns. Now column F is selected (shown in orange/red highlight), and the status bar shows "Selected: 1,048,576 rows, 1 column". Column F still displays "###" for most October dates, indicating it needs to be widened.
  
  I can see some October dates are partially visible (10/1/2022, 10/2/2022, etc.) but most rows show "###" because the column is too narrow.
  
  #### 情况分析与思考过程
  
  Now that I have only column F selected, I need to widen it to reveal all the October dates. The most reliable way to do this is to position the cursor precisely on the border between columns F and G in the header row, then drag it to the right.
  
  Looking at the header row, I can see:
  - Column F header is highlighted in orange
  - The border between F and G should be at the right edge of the F header
  
  I'll position my cursor on that border line and drag it to the right to widen column F. This should be around x=0.334 (the right edge of column F header) and I'll drag to about x=0.38 or further to ensure the dates are fully visible.
  
  Once column F is widened, I can proceed to identify and highlight all weekend cells across all five months with red background color (#ff0000).
  ```
- 操作:
  1. 按住鼠标左键从坐标 (0.334, 0.269) 拖动到坐标 (0.4, 0.269)

### 步骤 5:
- 描述:
  ```
  #### 重要信息
  
  The previous drag operation selected columns F, G, and H instead of resizing column F. The status bar shows "Selected: 1,048,576 rows, 3 columns" and these columns are highlighted in orange. Column F still displays "###" for October dates.
  
  I can see the calendar structure:
  - Column B: June 2022 (dates visible)
  - Column C: July 2022 (dates visible)  
  - Column D: August 2022 (dates visible)
  - Column E: September 2022 (dates visible)
  - Column F: October 2022 (still showing "###")
  
  #### 情况分析与思考过程
  
  The drag approach keeps selecting multiple columns instead of resizing. Let me try a different strategy:
  1. First, click somewhere neutral to deselect the current selection
  2. Then right-click on column F header to access column width options
  3. Or I can try double-clicking on the border between F and G to auto-fit the column width
  
  Let me try clicking on a neutral area first to deselect, then I'll use the Format menu to adjust column width, or try double-clicking on the column border which is a standard way to auto-fit column width in spreadsheet applications.
  
  Let me click on a neutral cell first to deselect.
  ```
- 操作:
  1. 左键单击坐标 (0.156, 0.417)

### 步骤 6:
- 描述:
  ```
  #### 重要信息
  
  The previous drag operation selected columns F, G, and H instead of resizing column F. The status bar shows "Selected: 1,048,576 rows, 3 columns" and these columns are highlighted in orange. Column F still displays "###" for October dates.
  
  I can see the calendar structure:
  - Column B: June 2022 (dates visible)
  - Column C: July 2022 (dates visible)  
  - Column D: August 2022 (dates visible)
  - Column E: September 2022 (dates visible)
  - Column F: October 2022 (still showing "###")

  1. First, click somewhere neutral to deselect the current selection
  2. Then right-click on column F header to access column width options
  3. Or I can try double-clicking on the border between F and G to auto-fit the column width

  Let me click on a neutral cell first to deselect.
  ```
- 操作:
  1. 左键单击坐标 (0.156, 0.417)

### 步骤 7:
- 描述:
  ```
  #### 重要信息
  
  The previous click successfully deselected the multiple columns. The spreadsheet now shows a neutral state with cell C7 selected (containing "05/07/2022"). Column F still displays "###" for October dates, indicating it needs to be widened to reveal the dates.
  
  I can see the calendar structure:
  - Column B: June 2022 (dates visible: 6/1/2022 through 6/30/2022)
  - Column C: July 2022 (dates visible: 7/1/2022 through 7/31/2022)
  - Column D: August 2022 (dates visible: 8/1/2022 through 8/31/2022)
  - Column E: September 2022 (dates visible: 9/1/2022 through 9/30/2022)
  - Column F: October 2022 (mostly showing "###" due to narrow width)
  
  #### 情况分析与思考过程
  
  Since the drag approach keeps selecting multiple columns instead of resizing, I should try a different method:
  1. Click on the Format menu in the menu bar
  2. Look for "Columns" or "Optimal Width" option
  3. Or I could right-click on column F header to access column width options
  
  Let me try clicking on the Format menu first to access column width adjustment options. This should give me more precise control over the column width.
  
  After widening column F, I'll need to:
  1. Identify all weekend dates (Saturdays and Sundays) for each month
  2. Select those cells and apply red background color (#ff0000)
  ```
  
  
- 操作:
  1. 左键单击坐标 (0.147, 0.069)

### 步骤 8:
- 描述:
  The Format menu is open. I can see the "Columns" option with an arrow indicating a submenu. Let me hover over it to see the column width options.
- 操作:
  1. 鼠标移动到坐标 (0.161, 0.256)

### 步骤 9:
- 描述:
  ```
  #### 重要信息
  
  The Format menu is open and I can see the "Columns" submenu with options including "Width..." and "Optimal Width...". This will allow me to adjust column F's width to reveal the October dates that are currently showing as "###".
  
  I can see the calendar structure:
  - Column B: June 2022 (dates visible)
  - Column C: July 2022 (dates visible)
  - Column D: August 2022 (dates visible)
  - Column E: September 2022 (dates visible)
  - Column F: October 2022 (mostly showing "###")
  
  #### 情况分析与思考过程
  
  The Format menu is open and I can see the Columns submenu. I should click on "Optimal Width..." to auto-fit column F so that the October dates become visible. This is more reliable than trying to drag the column border.
  
  After widening column F, I'll need to:
  1. Identify all weekend dates (Saturdays and Sundays) for each month
  2. Select those cells and apply red background color (#ff0000)
  
  Let me click on "Optimal Width..." option in the Columns submenu.
  ```
- 操作:
  1. 左键单击坐标 (0.332, 0.276)

### 步骤 10:
- 描述:
  ```
  #### 重要信息
  
  The "Optimal Column Width" dialog has appeared with:
  - Add: 0.20 cm (input field with adjustment buttons)
  - Default value checkbox (checked)
  - Help, Cancel, and OK buttons
  
  This dialog will auto-fit column F to its content, which should reveal the October dates that are currently showing as "###".
  
  #### 情况分析与思考过程
  
  I need to click the "OK" button to apply the optimal width to column F. This will automatically adjust the column width to fit the content (October dates).
  
  After clicking OK:
  1. Column F will be widened and October dates will be visible
  2. I can then proceed to identify all weekend dates (Saturdays and Sundays) across all 5 months
  3. Select those cells and apply red background color (#ff0000)
  
  Let me click the OK button to apply the optimal width.
  ```
- 操作:
  1. 左键单击坐标 (0.558, 0.556)

### 步骤 11:
- 描述:
  ```
  #### 重要信息
  
  The "Optimal Column Width" dialog has been closed and column F has been successfully widened. Now I can see all the October dates in column F (10/1/2022 through 10/31/2022). The calendar is now fully visible with all five months:
  - Column B: June 2022 (6/1/2022 - 6/30/2022)
  - Column C: July 2022 (7/1/2022 - 7/31/2022)
  - Column D: August 2022 (8/1/2022 - 8/31/2022)
  - Column E: September 2022 (9/1/2022 - 9/30/2022)
  - Column F: October 2022 (10/1/2022 - 10/31/2022)
  
  Now I need to identify and highlight all weekend dates (Saturdays and Sundays) with red background color (#ff0000).
  
  Weekend dates for each month:
  - June 2022: 6/4, 6/5, 6/11, 6/12, 6/18, 6/19, 6/25, 6/26
  - July 2022: 7/2, 7/3, 7/9, 7/10, 7/16, 7/17, 7/23, 7/24, 7/30, 7/31
  - August 2022: 8/6, 8/7, 8/13, 8/14, 8/20, 8/21, 8/27, 8/28
  - September 2022: 9/3, 9/4, 9/10, 9/11, 9/17, 9/18, 9/24, 9/25
  - October 2022: 10/1, 10/2, 10/8, 10/9, 10/15, 10/16, 10/22, 10/23, 10/29, 10/30
  
  #### 情况分析与思考过程
  
  Now that column F is widened and all dates are visible, I need to start highlighting the weekend cells. I'll work month by month:
  
  1. First, I'll select the June weekend cells (column B)
  2. Apply red background color to them
  3. Repeat for July, August, September, and October
  
  To select multiple cells, I can click on the first cell and then Ctrl+click on other cells to add them to the selection. Or I can select a range if the cells are consecutive.
  
  Let me start with June 2022 weekends. Looking at the calendar, I need to select cells B7 (6/4), B8 (6/5), B13 (6/11), B14 (6/12), B19 (6/18), B20 (6/19), B25 (6/25), B26 (6/26).
  
  Actually, looking more carefully at the visible rows, I need to identify which row corresponds to which date. Let me scroll up to see the beginning of the calendar to understand the row structure better.
  
  First, let me click on cell B3 to see where June starts.
  ```

  #### 重要信息
  
  Cell B3 is selected and shows "01/06/2022" (June 1, 2022) in the formula bar. Now I can see the full calendar layout clearly:
  
  - Row 3: June 1 (Wed), July 1 (Fri), August 1 (Mon), September 1 (Thu), October 1 (Sat)
  - Row 4: June 2 (Thu), July 2 (Sat), August 2 (Tue), September 2 (Fri), October 2 (Sun)
  
  I can now identify all weekend dates across all months:
  - June weekends: 6/4, 6/5, 6/11, 6/12, 6/18, 6/19, 6/25, 6/26
  - July weekends: 7/2, 7/3, 7/9, 7/10, 7/16, 7/17, 7/23, 7/24, 7/30, 7/31
  - August weekends: 8/6, 8/7, 8/13, 8/14, 8/20, 8/21, 8/27, 8/28
  - September weekends: 9/3, 9/4, 9/10, 9/11, 9/17, 9/18, 9/24, 9/25
  - October weekends: 10/1, 10/2, 10/8, 10/9, 10/15, 10/16, 10/22, 10/23, 10/29, 10/30
  
  #### 情况分析与思考过程
  
  Now I need to select and format all weekend cells with red background (#ff0000). I'll work systematically:
  
  1. First, select all June weekend cells using Ctrl+click to multi-select
  2. Apply red background to them
  3. Repeat for each month
  
  Let me start by clicking on cell B6 which contains 6/4 (Saturday) - the first weekend day in June. Then I'll Ctrl+click on other weekend cells to select them all at once.
  
  Looking at the visible rows:
  - Row 6: June 4 (Saturday) - cell B6
  - Row 7: June 5 (Sunday) - cell B7
  - Row 8: June 6 (Monday)
  
  So B6 is the first weekend cell. Let me click on it.
  
  I'll update the strategy tree to mark 1.2 as success since column F is now widened.

  #### 重要信息
  
  Cell B6 is now selected and shows "04/06/2022" (June 4, 2022 - Saturday) in the formula bar. This is the first weekend day of June 2022. I need to continue selecting all June weekend cells using Ctrl+click to multi-select them before applying the red background color.
  
  June 2022 weekend dates to select:
  - 6/4 (Saturday) - B6 ✓ (already selected)
  - 6/5 (Sunday) - B7
  - 6/11 (Saturday) - B12
  - 6/12 (Sunday) - B13
  - 6/18 (Saturday) - B18
  - 6/19 (Sunday) - B19
  - 6/25 (Saturday) - B24
  - 6/26 (Sunday) - B25
  
  #### 情况分析与思考过程
  
  I'll use Ctrl+click to add each weekend cell to the current selection. After selecting all June weekend cells, I'll apply the red background color (#ff0000) to them all at once, then move on to the next month.
  
  Let me continue by Ctrl+clicking on B7 (6/5 - Sunday) to add it to the selection.
  ```

  1. 左键单击坐标 (0.125, 0.403)，同时按住键 ctrl

### 步骤 14:
- 描述:
  ```
  #### 重要信息
  
  Cells B6 and B7 are now selected together (shown as "B6:B7" in the name box). The status bar shows "Selected: 2 rows, 1 column". This means I have successfully selected the first two weekend days of June (6/4 Saturday and 6/5 Sunday).
  
  I need to continue selecting the remaining June weekend cells:
  - B12 (6/11 - Saturday)
  - B13 (6/12 - Sunday)
  - B18 (6/18 - Saturday)
  - B19 (6/19 - Sunday)
  - B24 (6/25 - Saturday)
  - B25 (6/26 - Sunday)
  
  #### 情况分析与思考过程
  
  I'll continue using Ctrl+click to add each remaining weekend cell to the selection. After selecting all June weekend cells, I'll apply the red background color (#ff0000) to them all at once.
  
  Let me continue by Ctrl+clicking on B12 (6/11 - Saturday) to add it to the current selection.
  ```

### 步骤 15:
- 描述:
  ```
  #### 重要信息
  
  The previous Ctrl+click landed on B11 instead of B7. Currently, cell B11 is active (shown in the name box) and displays "09/06/2022" (June 9, 2022 - Thursday) in the formula bar. The status bar shows "Selected: 3 rows, 1 column" which suggests multiple cells are selected. 
  
  Looking at the calendar layout, I need to identify the correct weekend cells for June 2022:
  - June 4 (Saturday) - Row 6
  - June 5 (Sunday) - Row 7
  - June 11 (Saturday) - Row 12
  - June 12 (Sunday) - Row 13
  - June 18 (Saturday) - Row 18
  - June 19 (Sunday) - Row 19
  - June 25 (Saturday) - Row 24
  - June 26 (Sunday) - Row 25
  
  Currently, B11 (June 9, Thursday - NOT a weekend) is selected. I need to deselect it and select the correct weekend cells. Let me click on B11 with Ctrl to deselect it first, then properly select the June weekend cells.
  
  #### 情况分析与思考过程
  
  I need to correct the selection. B11 is June 9 which is a Thursday, not a weekend. Let me deselect it by Ctrl+clicking on it, then carefully select the correct weekend cells starting from B6 (June 4 - Saturday).
  
  After correcting the selection, I'll continue selecting all June weekend cells, apply red background to them, then repeat for July, August, September, and October.
  
  Let me first deselect B11 by Ctrl+clicking on it.

  I need to continue selecting the remaining June weekend cells using Ctrl+click.
  
  #### 情况分析与思考过程
  
  I need to add B13 (6/11 - Saturday) to the current selection. Let me Ctrl+click on cell B13 to add it to the selection.
  
  After selecting all June weekend cells (B6, B7, B13, B14, B19, B20, B25, B26), I'll apply red background color (#ff0000) to them, then repeat the process for July, August, September, and October.
