表名一定要写对

Dim tb As Table = e.Form.Controls("Table1").Table

Dim doc As New PrintDoc '定义一个新报表
Dim rt As New prt.RenderTable '定义一个新表格
Dim tb As Table = Tables("当日委托成交明细")
Dim ColNames() as string = "列名1,列名2,列名3".split(",")
rt.Width = "Auto" '表格宽度为自动,也就是等于各列设置宽度之和
rt.SplitHorzBehavior = prt.SplitBehaviorEnum.SplitIfNeeded '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.length - 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.AutoRotate = False '禁止自动旋转打印内容
doc.PageSetting.Landscape = True '横向打印

doc.Body.Children.Add(rt) '将表格加入到报表
doc.Preview()

doc.Body.Children.Add(rt) '将表格加入到报表
doc.Preview()
