--  [求助]专业报表,自动补空行(已解决)

根据狐爸老师在论坛的一段“自动补空行”的代码,移植过来(黄色标记)后不起作用,不知问题出在哪里,请各位老师指教,谢谢!!

这是狐爸老师的原代码:

 

Dim doc As New PrintDoc
Dim rt As New prt.RenderTable
Dim MinRows As Integer = 20
Dim tb As Table = Tables("表A")
For c As Integer = 0 To tb.Cols.Count -1 \'逐列填入内容
    rt.Cells(0,c).Text = tb.Cols(c).Name \'列名作为标题
    For r As Integer = 0 To tb.Rows.Count -1
        rt.Cells(r + 1, c).Text = tb(r,c)
    Next
    IF c = 0 Then \'加空行
        For  r As Integer = tb.Rows.Count To MinRows
            rt.Cells(r+1,0).Text = " "
        Next
    End If
Next
rt.Style.Gridlines.All = New prt.Linedef(Color.Gray) \'灰色网格线
doc.Body.Children.Add(rt)
doc.Preview()

谢谢czy老师,问题解决。看来专业报表太深奥了,变化无穷,并不像帮助里讲的那么简单,通过这一案例,也看到狐表的魅力,令人感慨万分。再次感谢czy老师的辛勤的劳动,让我们领略了狐表的风采。
