excel - 将 IF else 与 LEFT 组合以隐藏列

Question

如果某个范围内单元格的前 3 个字符等于另一个单元格的内容，我正在尝试编写一些代码来隐藏列。如果范围内的单元格为空，我有隐藏列的代码；-

Private Sub Worksheet_Change(ByVal Target As Range)

Dim r As Range, cell As Range
On Error GoTo ErrHandler
Set r = Me.Range("C8:R8")
Application.ScreenUpdating = False
Application.EnableEvents = False

For Each cell In r
    If cell.Value = "" Then
    cell.EntireColumn.Hidden = True
    Else
    cell.EntireColumn.Hidden = False

    End If

    Next

ErrHandler:
Application.ScreenUpdating = True
Application.EnableEvents = True

End Sub

以及识别单元格前 3 个字符的代码；-

Dim LResult As String

LResult = Left ("Alphabet",3)

但是如何将两者结合起来，引用特定的单元格而不是“字母表”？

无法让它工作 - 有什么建议吗？

Private Sub Worksheet_Change(ByVal Target As Range)

Dim r As Range, cell As Range

On Error GoTo ErrHandler
Set r = Me.Range("B7:CG7")

Application.ScreenUpdating = False
Application.EnableEvents = False

Row = 1
col = 1

For Each cell In r
  If cell.Value = "" And Left(cell.Value, 3) = cell(Row, col).Value Then
    cell.EntireColumn.Hidden = True
  Else
    cell.EntireColumn.Hidden = False

End If


Next
ErrHandler:
Application.ScreenUpdating = True
Application.EnableEvents = True
End Sub

干杯

您几乎已经有了工作代码。您正在将 cell.Value 与空字符串进行比较 - 现在只需对其应用 Left

LResult = Left (cell.Value,3)

编辑:

row = 20
col = 30

For Each cell In r
  If cell.Value = "" and  Left (cell.Value,3) = Cell(row, col).Value Then
    cell.EntireColumn.Hidden = True
  Else
    cell.EntireColumn.Hidden = False

End If

您想要从行和列的单元格中获取数据的位置(我使用 20、30 作为示例)
