求助：关于合并数据，怎么实现EXCEL表格跨列或者指定的列数据导入呢？

excel中有案件编号  案件类别  姓名  承办部门  承办人  承办日期  承办结果

但是实际使用中我只需要案件编号  姓名    承办结果

怎么实现跨列导入？并且比配案件基本信息表中的   案件编号  姓名   处理结果

Dim dlg As New OpenFileDialog \'定义一个新的OpenFileDialog

dlg.Filter= "Excel文件|*.xls|Access文件|*.mdb" \'设置筛选器

If dlg.ShowDialog = DialogResult.Ok Then \'如果用户单击了确定按钮

    Dim Book As New XLS.Book(dlg.FileName)

    Dim Sheet As XLS.Sheet = Book.Sheets(0)

    Tables("案件基本信息").StopRedraw()

    Dim nms() As String = {"案件编号","姓名"}

    For n As Integer = 1 To Sheet.Rows.Count -1

        Dim bh As String = sheet(n,0).Text

        Dim dr As DataRow = DataTables("案件基本信息").Find("案件编号 = \'" & bh & "\'")

        If dr Is Nothing Then \'如果不存在同编号的订单

            dr =  DataTables("案件基本信息").AddNew()

        End If

        For m As Integer = 0 To nms.Length - 1

            dr(nms(m)) = Sheet(n,m).Value

        Next

    Next

    Tables("案件基本信息").ResumeRedraw()

End If
