主题：专业报表代码为何会自动打印当前表隐藏列?

Dim tb as Table = Tables("订单")

Dim ColNames As New List(Of String)

For Each cl As Col In tb.Cols '排除隐藏列

   If cl.Visible Then

      ColNames.Add(cl.Name)

   End If

Next

rt.Width = "Auto" '表格宽度为自动,也就是等于各列设置宽度之和

rt.CanSplitHorz = True '表格宽度超出页宽时,可以水平换页

rt.Style.Font = tb.Font

For c As Integer = 0 To ColNames.Count - 1 '逐列设置和填入内容

    rt.Cells(0,c).Text = ColNames(c) '列名作为标题

    rt.Cells(0,c).Style.TextAlignHorz = prt.AlignHorzEnum.Center '标题内容水平居中

    rt.Cols(c).Width = tb.Cols(ColNames(c)).PrintWidth '列宽等于实际列宽

    If tb.Cols(ColNames(c)).IsNumeric Orelse tb.Cols(ColNames(c)).IsDate Then '如果是数值或日期列

        rt.Cols(c).Style.TextAlignHorz = prt.AlignHorzEnum.Right '数据水平靠右

    End If

    For r As integer = 0 To tb.Rows.Count -1 '开始填入该列内容

        rt.Cells(r + 1, c).Text = tb.Rows(r)(ColNames(c))

    Next

Next

rt.Style.Gridlines.All = New prt.Linedef(Color.Gray) '灰色网格线

rt.CellStyle.Spacing.All = 0.5 '单元格内距设为0.5毫米

rt.Rows(0).Style.TextAlignHorz = prt.AlignHorzEnum.Center '第一行内容水平居中

rt.RowGroups(0,1).Header = prt.TableHeaderEnum.All '利用行组,将第一行设为表头.

doc.Body.Children.Add(rt) '将表格加入到报表
