Excel数据验证 - 基于下拉值的Excel中的禁用单元格

Question

Excel表格中有2列。 A1包含一个下拉列表，其值为“启用”和“禁用”。需要根据A1下拉选项启用或禁用单元B1和C1。

我尝试使用数据验证，但它不起作用。任何人都可以建议我如何使用数据验证来实现这一目标吗？

          A     |   B
------------------------
1       Suggestions| (This cell should disable (B1))
------------------------
2       Errors| (Now here drop down will come with values(B2))
------------------------

当前VBA

  Private Sub Worksheet_Change(ByVal Target As Range)
     ThisRow = Target.Row
      If Target = Range("A1") Then
           If Target.Value = "Suggestions" Then
                Worksheets("Code Review").Range("B:C").Locked = True
            End If
      Else
         Worksheets("Code Review").Range("B:C").Locked = False
      End If 
     End Sub

也尝试过这样

    Private Sub Worksheet_Change(ByVal Target As Range)
    Dim cel As Range
    If Not Intersect(Range("A:A"), Target) Is Nothing Then
    Application.EnableEvents = False
    Me.Unprotect
    For Each cel In Intersect(Range("A:A"), Target)
        cel.Offset(ColumnOffset:=1).Resize(ColumnSize:=2).Locked = _
        cel.Value = "Suggestion"
    Next cel
    Me.Protect
    Application.EnableEvents = True
    End If

但这锁定了一切:(我只想锁定2个细胞。
