从范围中排除多个单元格

Question

我的问题是如何从范围对象中删除一个或多个单元格？之前我问过类似的问题，有人指出了这个问题：Remove cell from Range (object)

接受的答案：

Function getExcluded(ByVal rngMain As Range, rngExc As Range) As Range
    Dim rngTemp     As Range
    Dim rng         As Range

    Set rngTemp = rngMain
    Set rngMain = Nothing

    For Each rng In rngTemp
        If rng.Address <> rngExc.Address Then
            If rngMain Is Nothing Then
                Set rngMain = rng
            Else
                Set rngMain = Union(rngMain, rng)
            End If
        End If
    Next

    Set getExcluded = rngMain
End Function


Sub test()
    MsgBox getExcluded(Range("A1:M10000"), Range("a10")).Address
End Sub

接受的答案仅在排除范围是单个单元格的情况下有效-至少我尝试过的情况就是这样。我要排除的单元通常有一个以上的单元，因此我尝试修改代码：

我的尝试：

Function getExcluded(ByVal rngMain As Range, rngExcl As Range) As Range
    Dim rngTemp As Range
    Dim cellTemp As Range, cellExcl As Range

    Set rngTemp = rngMain
    Set rngMain = Nothing

    For Each cellTemp In rngTemp 'go through all cells in established range
        If Intersect(cellTemp, rngExcl) Is Nothing Then 'check for each cell if it intersects with the range to be excluded; no overlap -> put it into rngMain
            If rngMain Is Nothing Then
                Set rngMain = cellTemp
            Else
                rngMain = Union(rngMain, cellTemp)
            End If

            Debug.Print "cellTemp: " & cellTemp.Address
            Debug.Print "rngMain: " & rngMain.Address

        End If
    Next cellTemp

    Set getExcluded = rngMain


Sub test5()

    getExcluded(Range("A1:D3"), Range("B1:C1")).Select
End Sub

问题似乎出现在Set rngMain = Union(rngMain, rng)行中。我的Debug.Print语句告诉我cellTemp正在按应有的方式进行迭代；但是，即使执行Union的行并且无论cellTemp是什么，rngMain仍为$A$1

我做错了什么？

类似这样，也设置联合范围

Function testexclude(rngMain As Excel.Range, rngExclude As Excel.Range) As Excel.Range

Dim c As Excel.Range
Dim r As Excel.Range

For Each c In rngMain

    If Intersect(c, rngExclude) Is Nothing Then
        If r Is Nothing Then
            Set r = c
        Else
            Set r = Union(r, c)
        End If
    End If

Next c

Set testexclude = r

End Function
