Return 填充特定单元格时的行地址

Question

我有一些代码可以在任何 C:C 列被填充时 return 行地址。

Private Sub Worksheet_Change(ByVal Target As Range)
    Dim c As Range
    For Each c In Target.Cells
        If Not Intersect(c, Range("C:C")) Is Nothing Then
        Application.EnableEvents = False
            Range("A" & c.Row).Value = c.Address
        
        End If
    Next c
End Sub

我该如何添加到此代码中，以便仅在相邻 C:D:E 单元格以任意顺序填充时才会出现？因此，如果在 C5 中添加一个值，然后在 D5 中添加一个值，然后在 E5 中添加，它将 return 5:5 作为行地址，但只有在所有 3 个单元格都有值之后，如果仅填充 C5 和 D5，它才会' t火。

将代码复制到适当的 sheet 模块，例如Sheet1（选项卡名称在括号中）。

Option Explicit

' When done studying, out-comment or delete all the 'Debug.Print' lines
' except the one in the error-handling routine.

Private Sub Worksheet_Change(ByVal Target As Range)
    ' Use an error-handling routine to prevent exiting without enabling
    ' events in case of an error.
    On Error GoTo ClearError
    
    Const fRow As Long = 2
    Const cCols As String = "C:E"
    Const dCol As String = "A"
     
    Dim crg As Range
    Set crg = Columns(cCols).Resize(Rows.Count - fRow + 1).Offset(fRow - 1)
    Debug.Print "crg: " & crg.Address(0, 0)
    Dim irg As Range: Set irg = Intersect(crg, Target)
    
    If irg Is Nothing Then Exit Sub
    Debug.Print "irg: " & irg.Address(0, 0)
    
    Dim srg As Range: Set srg = Intersect(irg.EntireRow, crg)
    Debug.Print "srg: " & srg.Address(0, 0)
    
    ' I'm guessing that this is a too short operation since using
    ' the following line makes it kind of slow.

    ' Disable all events when writing to prevent retriggering the code.
    Application.EnableEvents = False

        For Each rrg In arg.Rows
            ' If the cell contains a fromula evaluating to ="",
            ' 'CountA' will count it. 'CountBlank' will consider it blank.
            If Application.CountBlank(rrg) = 0 Then
                RowString = CStr(rrg.Row)
                RowString = "'" & RowString & ":" & RowString
                rrg.EntireRow.Columns(dCol).Value = RowString
                Debug.Print "rrg: " & rrg.Address(0, 0) & " - " & RowString
            End If
        Next rrg
    Next arg

SafeExit:
     
    If Not Application.EnableEvents Then
        Application.EnableEvents = True ' enable all events when done writing
        'Application.ScreenUpdating = True ' too short operation
    End If
    
    Exit Sub ' don't forget this

ClearError:
    Debug.Print "Run-time error '" & Err.Number & "':" & Err.Description
    Resume SafeExit
End Sub


' Run this in VBE and see the results in the Immediate window ('Ctrl+G')

    Dim rg As Range: Set rg = Range("C2:E4,C6:E6,C8:E10")
    rg.Value = "Test"
