excel如何實作下拉方塊複選框？

EXCEL選擇下拉方塊實作複選框

第一步：新建一個excel且設定資料有效性【選取X列--資料--有效性】

第二步：開發工具--檢視程式碼--把程式碼複製進去保存就OK了

############################### ##程式碼如下：###

Private Sub Worksheet_Change(ByVal Target As Range)
' Developed by Contextures Inc.
' www.contextures.com
Dim rngDV As Range
Dim oldVal As String
Dim newVal As String
If Target.Count > 1 Then GoTo exitHandler
 
On Error Resume Next
Set rngDV = Cells.SpecialCells(xlCellTypeAllValidation)
On Error GoTo exitHandler
 
If rngDV Is Nothing Then GoTo exitHandler
 
If Intersect(Target, rngDV) Is Nothing Then
   'do nothing
Else
  Application.EnableEvents = False
  newVal = Target.Value
  Application.Undo
  oldVal = Target.Value
  Target.Value = newVal
  If Target.Column = 7 Then '这里规定好哪一列的数据有效性是多选的，A列是第1列，依次类推，如3就是C列，7就是G列
    If oldVal = "" Then
      'do nothing
      Else
      If newVal = "" Then
      'do nothing
      Else
        If InStr(1, oldVal, newVal) <> 0 Then  &#39;重复选择视同删除
          If InStr(1, oldVal, newVal) + Len(newVal) - 1 = Len(oldVal) Then &#39;最后一个选项重复
            Target.Value = Left(oldVal, Len(oldVal) - Len(newVal) - 1)
          Else
            Target.Value = Replace(oldVal, newVal & ",", "") &#39;不是最后一个选项重复的时候处理逗号
          End If
        Else &#39;不是重复选项就视同增加选项
        Target.Value = oldVal & "," & newVal
&#39;      NOTE: you can use a line break,
&#39;      instead of a comma
&#39;      Target.Value = oldVal _
&#39;        & Chr(10) & newVal
        End If
      End If
    End If
  End If
End If
 
exitHandler:
  Application.EnableEvents = True
End Sub
