连续打印关联表

示例

在示例文件的“类别”表中选定多行，然后执行下面的代码：

Dim doc As New Printdoc
Dim rx As prt.RenderText
Dim rt As prt.RenderTable
Dim Rows As List(Of DataRow)
Dim tbl As Table = Tables("类别")

For i as Integer = tbl.TopRow To tbl.BottomRow
    rx = New prt.RenderText
    rx.BreakBefore = prt.BreakEnum.Page '另起一页再打印
    rx.Style.FontSize = 14
    rx.Style.FontBold = True
    rx.Style.Spacing.Bottom = 5
    rx.Text = "类别: " & Tables("类别").Rows(i)("类别名称")
    doc.Body.Children.Add(rx)

    rt = New prt.RenderTable
    rt.Style.TextAlignHorz = prt.AlignHorzEnum.Center
    rt.Style.TextAlignVert = prt.AlignVertEnum.Center
    rt.Style.Borders.Bottom = New prt.LineDef(0.3,Color.LightGray)
    rt.CellStyle.Spacing.All = 1
    rt.Cols.Count = 4
    rt.Cells(0,0).Text = "产品名称"
    rt.Cells(0,1).Text = "单价"
    rt.Cells(0,2).Text = "库存量"
    rt.Cells(0,3).Text = "订购量"
    rt.Cells(0,4).Text = "再订购量"
    rt.Cells(0,5).Text = "中止"
    rt.rows(0).Style.Borders.Top = New prt.LineDef(1,Color.LightGray)
    rt.rows(0).Style.Borders.Bottom = New prt.LineDef(1,Color.LightGray)

    Rows = Tables("类别").Rows(i).DataRow.GetChildRows("产品")
    For r As integer = 0 To Rows.Count - 1
        rt.Cells(r+1,0).Text = rows(r)("产品名称")
        rt.Cells(r+1,1).Text = rows(r)("单价")
        rt.Cells(r+1,2).Text = rows(r)("库存量")
        rt.Cells(r+1,3).Text = rows(r)("订购量")
        rt.Cells(r+1,4).Text = rows(r)("再订购量")
        If rows(r)("中止") = True Then
            Dim rm As New prt.RenderImage
            rm.Image = getImage("Check.Ico")
            rm.Style.ImageAlign.AlignHorz = prt.ImageAlignHorzEnum.Center
            rm.Style.ImageAlign.StretchHorz = False
            rm.Style.ImageAlign.StretchVert = False
            rt.Cells(r+1,5).RenderObject = rm
        End If
    Next

    doc.Body.Children.Add(rt)
    rx = New prt.RenderText
    rx.Style.FontBold = True
    rx.Style.Spacing.Top = 3
    rx.Text = "产品数目: " & Rows.Count
    rx.Style.TextAlignHorz = prt.AlignHorzEnum.Right
    doc.Body.Children.Add(rx)
Next
doc.Preview
