将IF else与LEFT组合以隐藏列

Question

如果某个范围中单元格的前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。如果范围中的单元格为空，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

用于识别单元格的前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，引用一个特定的单元格而不是“Alphabet”？

不能让这个工作 - 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

Answer 1

你几乎有工作代码。您正在将cell.Value与空字符串进行比较 - 现在只需将Left应用于它

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

你想要来自行和col的单元格的数据（我使用20,30作为例子）
