主题：用帮助里面的代码 网页页面不显示数据

系统已经手动增加了 订单 这个外部表，外部表默认加载全部数据 网页会显示数据。用 _identify is null设置了筛选不加载任何数据，用帮助里面的代码，网页不显示数据。如何外部表不加载数据，用下述代码 网页也可以显示数据？

Select Case e.Path

    Case "table.htm"

        Dim wb As New WeUI

        With wb.AddTable("","Table1")

            .Alternate = 3

            .RowHead = 1

            .ColWidth = "12px"

            Dim nms() As String = {"","产品","客户","数量","单价","日期"}

            .Head.AddRow(nms)

            Dim cnt As Integer

            For Each r As DataRow In DataTables("订单").Select("数量 > 100", "日期 Desc")

                cnt = cnt + 1

                With .Body.AddRow(cnt, r("产品"), r("客户"), r("数量"))

                    .AddCell(Format(r("单价"), "#0.00"))

                    .AddCell(Format(r("日期"), "MM月dd日"))

                End With

            Next

        End With

        e.WriteString(wb.Build)

End Select
