excel - 多个条目下拉列表：换行符而不是逗号

Question

我正在使用教程中的 vba 代码来允许 excel 下拉列表中的多个条目。

该代码工作正常，但它为新条目添加了一个逗号。我希望每个新条目都换行而不是逗号。

所以，而不是a,b,c

我想

a
b
c

有什么建议吗？

这是代码

Option Explicit

Private Sub Worksheet_Change(ByVal Target As Range)
Dim rngDV As Range
Dim oldVal As String
Dim newVal As String
Dim lUsed As Long
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
Else
Application.EnableEvents = False
newVal = Target.Value
Application.Undo
oldVal = Target.Value
Target.Value = newVal
If Target.Column = 13 Then
If oldVal = "" Then
Else
If newVal = "" Then
Else
lUsed = InStr(1, oldVal, newVal)
If lUsed > 0 Then
Target.Value = oldVal
Else
Target.Value = oldVal _
& ", " & newVal
End If

End If
End If
End If
End If

exitHandler:
Application.EnableEvents = True
End Sub
