如何实现基于触发词的对应列指定单元格区域条件格式设置？

Got it, let's solve this exactly how you need it—no messy workarounds, just straight-up solutions that trigger highlighting when you type "Week 1" or "Week 2" in those top cells, ignoring whatever's in the lower range. Here are two reliable approaches:

Solution 1: Conditional Formatting (No Macros Needed)

This is the simplest method since it uses Excel's built-in tools, no need to enable macros.

First, select all the cells you want to be eligible for highlighting (e.g., B4:B12, C4:C12, ..., or drag to select the entire block from row 4 to row 12 across your target columns).
Go to the Home tab → click Conditional Formatting → select New Rule.
In the rule dialog, choose "Use a formula to determine which cells to format".
Paste this formula into the input box:
```
=OR(INDEX($3:$3, COLUMN())="Week 1", INDEX($3:$3, COLUMN())="Week 2")
```
What this does: It checks the cell in row 3 of the same column as the current cell. If that top cell is "Week 1" or "Week 2", the formatting applies.
Click the Format button, switch to the Fill tab, pick your preferred highlight color, then hit OK.
Click OK again to save the rule.

Now, whenever you type "Week 1" or "Week 2" in any cell in row 3, the corresponding column's rows 4-12 will light up automatically.

Solution 2: VBA Macro (Real-Time Trigger & Flexible Control)

If you want more flexibility (like adjusting the highlight range or adding custom formatting later), a simple VBA macro works perfectly.

Right-click the worksheet tab (e.g., "Sheet1") and select View Code.

Paste this code into the VBA editor window:

Private Sub Worksheet_Change(ByVal Target As Range)
    ' Only react to changes in row 3 (your top header row)
    If Target.Row = 3 Then
        Dim targetCol As Integer
        targetCol = Target.Column
        
        ' Define the range to highlight (rows 4 to 12 in the modified column)
        Dim highlightRange As Range
        Set highlightRange = Me.Range(Me.Cells(4, targetCol), Me.Cells(12, targetCol))
        
        ' Check if the input is "Week 1" or "Week 2" (case-insensitive)
        If UCase(Target.Value) = "WEEK 1" Or UCase(Target.Value) = "WEEK 2" Then
            ' Set your highlight color (RGB value can be adjusted)
            highlightRange.Interior.Color = RGB(255, 255, 0) ' Bright yellow
        Else
            ' Clear formatting if the top cell doesn't match
            highlightRange.Interior.ColorIndex = xlColorIndexNone
        End If
    End If
End Sub

Close the VBA editor, and save your workbook as a .xlsm file (since it contains macros).

This macro triggers instantly when you edit any cell in row 3—no manual refreshes needed. You can tweak the row numbers (4 to 12) or RGB color code to match your exact needs.
