标题：统计打印

Dim doc As PrintDoc = e.Form.GernatePrintDoc()
doc.Preview()

这句代码是打印这个窗口的，

'Dim grp As WinForm.table = e.Form.Controls("Table1")
'Dim doc As PrintDoc = e.Form.GernatePrintDoc(grp)
'doc.Preview()

这句代码会报错的，麻烦给给正常的代码谢谢

Dim doc As New PrintDoc
Dim tb As Table = Tables("统计查询_Table1")
Dim prs As Integer = 40 '每页20行
For p As Integer = 0 To math.Ceiling(tb.Rows.Count / prs) - 1
    Dim rt As New prt.RenderTable
    rt.Style.Gridlines.All = New prt.Linedef(Color.Gray)
    rt.CellStyle.Spacing.All = 0.5
    For c As Integer = 0 To tb.Cols.Count - 1
        rt.Cells(0, c).Text = tb.Cols(c).Name
        For r As Integer = p * prs To math.min(tb.Rows.Count - 1, ( p + 1) * prs - 1)
            rt.Cells(r - p * prs + 1, c).Text = tb.rows(r)(c)
        Next
    Next
    If p < math.Ceiling(tb.Rows.Count / prs) - 1 Then
        rt.BreakAfter = prt.BreakEnum.Page
    End If
    doc.Body.Children.Add(rt)
Next
doc.Preview()

老师刚刚我用这个方法实现了，，但是列宽要在在那个位置设置，，，还有隐藏的列不想打印，怎么设置，，给调整一下代码呗，谢谢

老师你给的这句代码好像就是隐藏了数据，，格子还在，，页面左右上下间距是怎么设置的，麻烦再统计窗口的打印给调试一下，我学习学习
