    For Each fl As String In dlg.FileNames
        Dim Book As New XLS.Book(fl)

        Tables("明细表").StopRedraw()
        '注意以下数组中列名称的顺序,必须和Excel表中的列顺序一致
        Dim nms() As String ={"卡号","交易时间","金额","数量"}
        '注意下面的循环变量从1开始,而不是从0开始,因为Excel表的第一行是标题
        Dim Sheet As XLS.Sheet = Book.Sheets(0)
        For n As Integer = 4 To Sheet.Rows.Count -1
            Dim sj As String = sheet(n,2).Text

            If DataTables("明细表").Find("交易时间 = '" & sj & "'") Is Nothing Then '如果不存在同编号的订单
                Dim r As Row = Tables("明细表").AddNew()
                For m As Integer = 0 To nms.Length - 1
