标题：如何将表B的列标题写入到表A的第一行?

下面的代码结果是将最后一列的标题全部写入到第一行了,我要的结果是表A第一列写入表B的第一列标题,表A第二列写入表B的第二列标题,以此类推
Dim dr As DataRow = DataTables("表B").DataRows(0)
For Each c As DataCol In DataTables("表B").DataCols
For Each cl As DataCol In DataTables("Sheet6").DataCols
dr(c)=cl.Name
Next
Next

Dim dr As DataRow = DataTables("表A").DataRows(0)
dim tt as string
For Each c As DataCol In DataTables("表B").DataCols
      tt = tt & "|" & c.name
Next
dim n as integer
For Each cl As DataCol In DataTables("表A").DataCols
    dr(cl)=tt.split("|")(n+1)
    n=n+1
Next

刚才A  B 表颠倒了

谢谢mr725老师!

简化一下:::::::::::::

Dim dr As DataRow = DataTables("表A").DataRows(1)
Dim tt as string
Dim n as integer
For Each c As DataCol In DataTables("表B").DataCols
    tt = c.name
    dr(Tables("表A").Cols(n).name)=tt
    n=n+1
Next

yangming版主,我可当不了老师,  只是刚好写过类似的代码, 好多都不会的~  

能者为师,,这段代码我搞了二天也没搞出来,就是没想到复制为文本再提取,有时候就是这么笨,呵呵

这个好,呵

我参考楼主的代码：
改成这样：
Dim tt1 as string
Dim tt2 as string
For Each c As DataCol In DataTables("表B").DataCols
      tt1 = tt1 & "|" & c.name
      tt2 = tt2 & "|" & c.Caption
Next
Dim Values1() as String
Dim Values2() as String
Values1 = tt1.split("|")
Values2 = tt2.split("|")
Dim dr1 As DataRow = DataTables("表A").AddNew()
Dim dr2 As DataRow = DataTables("表A").AddNew()
Dim n as integer
For Each cl As DataCol In DataTables("表A").DataCols
    IF Values1.Length > (n+1) Then
        dr1(cl)=tt1.split("|")(n+1)
        dr2(cl)=tt2.split("|")(n+1)
        n=n+1
    ELSE
        dr1(cl)=Nothing
        dr2(cl)=Nothing
    END IF
Next

 类似：  

For Each dt As DataTable In DataTables

    For Each dc As DataCol In dt.DataCols

        Dim dr As DataRow = DataTables("表A").AddNew()

        dr("表名")=dt.Name

        dr("表标题")=dt.caption

        dr("列名")=dc.Name

        dr("列标题")=dc.caption

    Next

Next

如果是：一次就把项目中所有表名、表标题、列名、列标题全部填入到表A，请问怎样改写以下代码Dim tt1 as string
Dim tt2 as string
For Each c As DataCol In DataTables("表B").DataCols
      tt1 = tt1 & "|" & c.name
      tt2 = tt2 & "|" & c.Caption
Next
Dim Values1() as String
Dim Values2() as String
Values1 = tt1.split("|")
Values2 = tt2.split("|")
Dim dr1 As DataRow = DataTables("表A").AddNew()
Dim dr2 As DataRow = DataTables("表A").AddNew()
Dim n as integer
For Each cl As DataCol In DataTables("表A").DataCols
    IF Values1.Length > (n+1) Then
        dr1(cl)=tt1.split("|")(n+1)
        dr2(cl)=tt2.split("|")(n+1)
        n=n+1
    ELSE
        dr1(cl)=Nothing
        dr2(cl)=Nothing
    END IF
Next

For Each dt As DataTable In DataTables
    For Each dc As DataCol In dt.DataCols
        Dim dr As DataRow = DataTables("表A").AddNew()
        dr("表名")=dt.Name
        dr("表标题")=dt.caption
        dr("列名")=dc.Name
        dr("列标题")=dc.caption
    Next
Next
这个不就可以吗?

另外,要按楼上的改,那么表A你得事先准备好增加列 =  表个数 X 每个表的列数 ,多麻烦啊~   对不?
