看着帮助中的：
1，sql语句
2，分组
3，绑定

能力有限而写不出来了....

因为项目是不断（减小或增加） 为了避免当增加1个项目，就要更改表结构和报表。

帮助中基本是取关系表中相关的所有数据，但没有按条件取关联表的数据，接着分别填到不同的列中的实例啊。。。。

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

学习，谢谢分享！

改全部用foxtable的语言写：（因用外部数据库，打印前已加载数据，再用select语句从后台找数据是效率的重复）

呵呵，目前在论坛，专业报表你是研究得最好的了，你搞不定的，估计也没有人能帮上手的。
