代码

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
  //在第几列写几
  If Target.Column = 5 Then
    If oldVal = "" Then
      Else
      If newVal = "" Then
        Else
        If InStr(oldVal, newVal) > 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
