分组打印怎么实现选择打印哪些列？并自定义设置列宽？
当前是以地区进行分组显示，怎么实现根据地区和客户名称进行组合分组显示呢？
Dim doc As New PrintDoc
Dim rt As Prt.RenderTable
Dim rx As prt.RenderText
Dim tbl As Table = Tables("客户")
Dim Rows As List(Of DataRow)
Dim Regions As List(Of String) = tbl.DataTable.GetValues("地区")
doc.Pagesetting.LandScape = True
For Each Region As String In Regions
    rx = New prt.RenderText
    rx.Style.FontSize = 14
    rx.Style.FontBold = True
    rx.Style.Spacing.Bottom = 2
    rx.Text = "地区: " & Region
    doc.Body.Children.Add(rx)
    rt = New prt.RenderTable
    rt.Style.Font = Tables("客户").Font
    rt.Style.TextAlignVert = prt.AlignVertEnum.Center
    rt.Style.GridLines.All = New prt.LineDef(0.3,Color.LightGray)
    rt.Style.Spacing.Bottom = 5
    rt.CellStyle.Spacing.All = 1
    rt.Style.Font = tbl.Font
    Rows = tbl.Datatable.Select("[地区] = \'" & Region & "\'")
    For c As integer = 0 To tbl.Cols.Count - 1
        rt.Cells(0,c).Text = tbl.Cols(c).Name
        rt.Cols(c).Width = tbl.Cols(c).PrintWidth
        For r As integer = 0 To Rows.Count -1
            rt.Cells(r + 1, c).Text = rows(r)(tbl.Cols(c).Name)
        Next
    Next
    rt.RowGroups(0,1).Header = prt.TableHeaderEnum.All
    doc.Body.Children.Add(rt)
Next
doc.preview()

代码如下，运行效果，是一个记录一行不是想要的我想实现的是

一个班级一张总表
分别按照学生姓名分组显示与该学生姓名相关的记录

然后再显示第二个班的

麻烦老师继续指导下谢谢

代码如下：

Dim doc As New PrintDoc
Dim rt As Prt.RenderTable
Dim rx As prt.RenderText
Dim tbl As Table = Tables("学生信息登记")
Dim Rows As List(Of DataRow)
Dim Regions As List(Of String()) = tbl.DataTable.GetValues("学校|年级|班级")
doc.Pagesetting.LandScape = True
For Each Region As String() In Regions
rx = New prt.RenderText
rx.Style.FontSize = 14
rx.Style.FontBold = True
rx.Style.Spacing.Bottom = 2
rx.Text = "班级: " & Region(0) & Region(1) & Region(2)
doc.Body.Children.Add(rx)
rt = New prt.RenderTable
rt.Style.Font = Tables("学生信息登记").Font
rt.Style.TextAlignVert = prt.AlignVertEnum.Center
rt.Style.GridLines.All = New prt.LineDef(0.3,Color.LightGray)
rt.Style.Spacing.Bottom = 5
rt.CellStyle.Spacing.All = 1
rt.Style.Font = tbl.Font
\'Rows = tbl.DataTable.Select("[学校] = \'" & Region(0) & "\' and 年级=\'" & Region(1) & "\'and 班级=\'" & Region(2) & "\'and 学生姓名=\'" & Region(3) & "\'")
Rows = tbl.DataTable.Select("[学校] = \'" & Region(0) & "\' and 年级=\'" & Region(1) & "\'and 班级=\'" & Region(2) & "\'")
Dim nms() As String = {"学生姓名","亲属姓名","与学生关系","身份证号","联系电话","现居住地"}
For c As Integer = 0 To nms.length - 1
rt.Cells(0,c).Text = tbl.Cols(nms(c)).Name
rt.Cols(c).Width = tbl.Cols(nms(c)).PrintWidth
For r As Integer = 0 To Rows.Count -1
rt.Cells(r + 1, c).Text = rows(r)(tbl.Cols(nms(c)).Name)
Next
Next

rt.RowGroups(0,1).Header = prt.TableHeaderEnum.All
doc.Body.Children.Add(rt)
Next
doc.preview()

上面的代码就是一个班级一张表的。如果只有一行是数据没有加载完整吧

--  回复：（有点蓝）上面的代码就是一个班级一张表的。如...

通过下拉框选择对应的值然后导入表到窗体表中
Dim tb1 As WinForm.Table = e.Form.Controls("Table1")
Dim c1 As WinForm.ComboBox = e.Form.Controls("选择表")
Dim cmd1 As New SQLCommand
Dim dt1 As DataTable
cmd1.C
cmd1.CommandText = "SEL ECT * From {" & c1.Value & "} "
dt1 = cmd1.ExecuteReader(True)
tb1.Table.DataSource =dt1
Dim tab3 As WinForm.TabControl = e.Form.Controls("卡片管理")
tab3.SelectedPage.Text= "【" & c1.value & "】一览表"
_tablename=c1.Value.Trim()

经过一系列筛选操作后，窗体表只显示了一个年级一个班级的数据
新增一个按钮代码事件如下【没有打印窗体表中已经筛选出来的数据而是打印了表中的所有数据，有没有办法限制只打印表中经过筛选后的数据呢？】
\'Dim c1 As WinForm.ComboBox = e.Form.Controls("选择表")
\'Dim tb1 As WinForm.Table = e.Form.Controls("Table1")
\'With tb1.Table.PrintInfo
\'.Title = c1.Value
\'.PageFooter = "第[PageNo]页,共[PageCount]页"
\'.PageFooterLine = True
\'.PaperKind = 9
\'.FitIntoPage = True
\'End With
\'tb1.Table.Print(True,True)

Dim doc As New PrintDoc
Dim rt As Prt.RenderTable
Dim rx As prt.RenderText
Dim tbl As Table = Tables("学校数据管理_table1")
Dim Rows As List(Of DataRow)
Dim Regions As List(Of String()) = tbl.DataTable.GetValues("学校|年级|班级")
doc.Pagesetting.LandScape = True
For Each Region As String() In Regions
rx = New prt.RenderText
rx.Style.FontSize = 14
rx.Style.FontBold = True
rx.Style.Spacing.Bottom = 2
rx.Text = "班级: " & Region(0) & Region(1) & Region(2)
doc.Body.Children.Add(rx)
rt = New prt.RenderTable
rt.Style.Font = Tables("学校数据管理_table1").Font
rt.Style.TextAlignVert = prt.AlignVertEnum.Center
rt.Style.GridLines.All = New prt.LineDef(0.3,Color.LightGray)
rt.Style.Spacing.Bottom = 5
rt.CellStyle.Spacing.All = 1
rt.Style.Font = tbl.Font
\'Rows = tbl.DataTable.Select("[学校] = \'" & Region(0) & "\' and 年级=\'" & Region(1) & "\'and 班级=\'" & Region(2) & "\'and 学生姓名=\'" & Region(3) & "\'")
Rows = tbl.DataTable.Select("[学校] = \'" & Region(0) & "\' and 年级=\'" & Region(1) & "\'and 班级=\'" & Region(2) & "\'")
Dim nms() As String = {"学生姓名","亲属姓名","与学生关系","身份证号","联系电话","现居住地"}
For c As Integer = 0 To nms.length - 1
rt.Cells(0,c).Text = tbl.Cols(nms(c)).Name
rt.Cols(c).Width = tbl.Cols(nms(c)).PrintWidth
For r As Integer = 0 To Rows.Count -1
rt.Cells(r + 1, c).Text = rows(r)(tbl.Cols(nms(c)).Name)
Next
Next

rt.RowGroups(0,1).Header = prt.TableHeaderEnum.All
doc.Body.Children.Add(rt)
Next
doc.preview()

打印按钮代码运行后的效果，数据是全部加载的但是显示不全
