主题：(请教)这个报表的代码应怎么样写

试了1天1晚时间了，终于写出来了（分享1下):

dim barow as row = tables("表A").current
dim babianhao as string = barow("编号")

Dim doc As New Printdoc
Dim rt As New prt.RenderTable

dim af as table = Tables("表A.表F")
With Tables("表A.表F")
rt = New prt.RenderTable
rt.Style.GridLines.All = prt.Linedef.Default '网格线为默认类型
For n As integer = 0 To .Rows.Count - 1      
    rt.Cells(0,0).Text = "编号"
    rt.Cells(0,1).Text ="采样编号"   
    rt.Cells(0,2+n).Text = .rows(n)("项目")

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
   cmd.CommandText = "Select 编号,采样编号,值 from {表C} where 编号 = '"& babianhao &"' and 项目= '"& Tables("表A.表F").rows(n)("项目") &"' "
   dt = cmd.ExecuteReader() '生成一个临时表
   For r As integer = 0 To dt.DataRows.Count - 1
        rt.Cells(r+1,0).Text = dt.DataRows(r)("编号")
        rt.Cells(r+1,1).Text = dt.DataRows(r)("采样编号")
        rt.Cells(r+1,2+n).Text = dt.DataRows(r)("值")
   Next

next
End With
doc.Body.Children.Add(rt)
doc.Preview
