Excel编程中关于跨列单元格的自适应高度的解决办法

今天修改一个用Excel的报表,有一个数据格是跨两列,一般单格的数据格用自动换行就可以实现自适应高度,但是跨列是不行的.查找google良久,也没发现适合的办法,一阵头痛之后,突然有了灵感,于是马上做试验,还真的实现了.先写出来,如果有困于这个问题的朋友偶然路过,或许还能有一点用处.
原理:在另外一个sheet里面利用单元格换行和自适应高度的特性,将一个试验单元格宽度设置成实际跨列单元格的宽度,然后将需要输入的字符放入该试验单元格,取得高度返回给实际跨列单元格就可以了.

以下是vb的代码
Private Sub Command1_Click()
      Dim objExcel As New Excel.Application
      Dim wkSheet As Excel.Worksheet
      objExcel.Workbooks.Open "E:\book1.xls"

      Set wkSheet = Worksheets("Sheet1")
      wkSheet.Select
      Dim iWidth As Double
      iWidth = wkSheet.Columns("A:A").ColumnWidth + wkSheet.Columns("B:B").ColumnWidth
     
       Set wkSheet = Worksheets("Sheet2")
       wkSheet.Select
       wkSheet.Columns("A:A").ColumnWidth = iWidth
     
       Range("A1").Select
        With Selection
            .HorizontalAlignment = xlGeneral
            .VerticalAlignment = xlCenter
            .WrapText = True
            .Orientation = 0
            .AddIndent = False
            .IndentLevel = 0
            .ShrinkToFit = False
            .ReadingOrder = xlContext
            .MergeCells = False
        End With
       
        ActiveCell.Value = "dsfsdafsdafasfsdafsadfdsafsdafa"
        Dim iHeight As Double
        iHeight = ActiveCell.RowHeight

        Set wkSheet = Worksheets("Sheet1")
        wkSheet.Select
        Range("A1:B1").Select
       
        With Selection
            .HorizontalAlignment = xlGeneral
            .VerticalAlignment = xlCenter
            .WrapText = True
            .Orientation = 0
            .AddIndent = False
            .IndentLevel = 0
            .ShrinkToFit = False
            .ReadingOrder = xlContext
            .MergeCells = True
        End With
        Rows("1:1").Select
        Selection.RowHeight = iHeight
       
        Range("A1:B1").Select
        ActiveCell.Value = "dsfsdafsdafasfsdafsadfdsafsdafa"
       
        objExcel.ActiveWorkbook.SaveAs "e:\book2.xls"
        objExcel.AlertBeforeOverwriting = False
        objExcel.Quit
End Sub
