自己指定需要打印的列名不就行了,如
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("订单")
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
dim cls() as string = {"产品","数量","金额"}
For c As Integer = 0 To cls.length -1 '逐列设置和填入内容
rt.Cells(0,c).Text = tb.Cols(cls(c)).Name '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(cls(c)).PrintWidth '列宽等于实际列宽
If tb.Cols(cls(c)).IsNumeric Orelse tb.Cols(cls(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(r,tb.Cols(cls(c)).index)
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
doc.Preview()
