VBA 实现excel单元格多选

Sub Worksheet_Change(ByVal Target As Range)
'让数据有效性选择 可以多选,不可重复
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
If Target.Column = 2 Or 3 Or 6 Then '数字是你想要多选的列是多少，多个用or连接。
Application.Undo
oldVal = Target.Value
Target.Value = newVal
If oldVal = "" Then
Else
If newVal = "" Then
Else '去除重复的字段
If InStr(1, oldVal, newVal) <> 0 Then
If InStr(1, oldVal, newVal) + Len(newVal) - 1 = Len(oldVal) Then '最后一个选项重复
Target.Value = Left(oldVal, Len(oldVal) - Len(newVal) - 1)
Else
Target.Value = Replace(oldVal, newVal & ",", "") '不是最后一个选项重复的时候处理逗号
End If
Else '不是重复选项就视同增加选项
Target.Value = oldVal _
& "," & newVal '可以是任意符号隔开
End If
End If
End If
End If
End If
exitHandler:
Application.EnableEvents = True
End Sub
