表结构不一样：

If e.DataCol.name=" 变动类型"then
    If e.newvalue Is Or Nothing Then
        Dim nma() As String = {"A1","A2","A3","A4"} 'A表数据来源列
        Dim nmb() As String = {"B1","B2","B3","B4"} 'B表数据接收列
        Dim dr As DataRow = DataTables("表B").AddNew
        For i As Integer = 0 To nma.Length - 1
            dr(nmb(i)) = e.DataRow(nma(i))
        Next
    End If
End If
