主题：打印后台数据的排序问题

采用SQLCommand的ExecuteReader方法，生成一个临时表

不能用  Tables("XX").Sort = "XXX"方式进行排序号。

希望在打印是按序号列排序，该怎么改代码？

 

Dim doc As New PrintDoc
Dim rt As New prt.RenderTable
Dim cmd As New SQLCommand '定义一个SQL命令
Dim dt As DataTable '定义一个数据表变量
Dim Count As Integer = 0
cmd.CommandText = "Select * From {订单} Where Year(日期) = 2009 And Month(日期) = 6"
dt = cmd.ExecuteReader() '生成一个临时表
For Each Col AS DataCol In Dt.DataCols
    rt.Cells(0,Count).Text = Col.Name
    For r As integer = 0 To dt.DataRows.Count - 1
        rt.Cells(r +1,Count).Text = dt.DataRows(r)(Col.Name)
    Next
    Count = Count + 1
Next
rt.Style.Gridlines.All = New prt.Linedef(Color.Gray) '灰色网格线
rt.CellStyle.Spacing.All = 1 '内容距离网格线1毫米
rt.Rows(0).Style.TextAlignHorz = prt.AlignHorzEnum.Center '第一行内容水平居中
doc.Body.Children.Add(rt)
doc.Preview()

谢谢

为什么没有按序排列？

我已经排序了呀？
