好像帮助中没有找到这段 “  隐藏统计表1 统计表2   生成新的合并统计表，然后重置表头，显示出来”

看11楼。你12楼什么意思？没看懂

Dim sql As String = "selec t 摘要_类型, 时间, 收入, 支出 from {现金日记账} u nion all selec t 摘要_类型, 时间, 收入, 支出 from {银行日记账}"

Dim bd1 As New CrossTableBuilder("统计表1", sql)
bd1.HGroups.AddDef("摘要_类型")
bd1.VGroups.AddDef("时间", DateGroupEnum.Year, "{0}年")
bd1.VGroups.AddDef("时间", "{0}月")
bd1.Totals.AddDef("收入", "收入")
bd1.Totals.AddDef("支出", "支出")
bd1.VerticalTotal = True
bd1.FromServer = True
bd1.Filter = "时间 is not null"

Tables("日记账_Table1").DataSource = bd1.BuildDataSource '将统计结果绑定到Table

With DataTables("日记账_Table1").DataCols  '用表达式列计算库存数据
    .Add("收入",Gettype(Double))
    .Add("支出",Gettype(Double))
End With

For Each r As Row In Tables("日记账_Table1").Rows
    Dim sum1 As Double = 0
    Dim sum2 As Double =0
    For Each c As Col In Tables("日记账_Table1").Cols
        If c.Caption Like "*_收入*" Then
            sum1 += r(c.name)
        ElseIf c.Caption Like "*_支出*" Then
            sum2 += r(c.name)
        End If
    Next
    r("收入") = sum1
    r("支出") = sum2
Next

 

 

老师，我是想表示 这段代码前面是做的表头，后面显示出来 表头就没有了（年份月份就没有了） 还要再从做个表头，好像帮助中没有这段重做 合计的这个表头的 教程，还是我没有找到

老师为什么合并统计窗口的表头 和 打印 预览的表头 不一样呢

Dim sql As String = "sele ct 摘要_类型, 时间, 收入, 支出 from {现金日记账} u nion all sel ect 摘要_类型, 时间, 收入, 支出 from {银行日记账}"

Dim bd1 As New CrossTableBuilder("统计表1", sql)
bd1.HGroups.AddDef("摘要_类型")
bd1.VGroups.AddDef("时间", DateGroupEnum.Year, "{0}年")
bd1.VGroups.AddDef("时间", "{0}月")
bd1.Totals.AddDef("收入", "收入")
bd1.Totals.AddDef("支出", "支出")
bd1.VerticalTotal = True
bd1.FromServer = True
bd1.Filter = "时间 is not null"

Tables("日记账_Table1").DataSource = bd1.BuildDataSource '将统计结果绑定到Table

With DataTables("日记账_Table1").DataCols  '用表达式列计算库存数据
    .Add("收入",Gettype(Double))
    .Add("支出",Gettype(Double))
End With

For Each r As Row In Tables("日记账_Table1").Rows
    Dim sum1 As Double = 0
    Dim sum2 As Double =0
    For Each c As Col In Tables("日记账_Table1").Cols
        If c.Caption Like "*_收入*" Then
            sum1 += r(c.name)
        ElseIf c.Caption Like "*_支出*" Then
            sum2 += r(c.name)
        End If
    Next
    r("收入") = sum1
    r("支出") = sum2
Next

Dim dt As DataTable
dt = bd1.Build(True)
Dim doc As New PrintDoc
Dim rt As New prt.RenderTable
Dim Count As Integer = 0
For Each Col As DataCol In Dt.DataCols
    rt.Cells(0,Count).Text = Col.Name
    For r As Integer = 0 To dt.DataRows.Count - 1
        rt.Cells(r +1,Count).Text = dt.DataRows(r)(Col.Name)
    Next
    Count = Count + 1
Next
rt.Style.Gridlines.All = New prt.Linedef(Color.Gray)
rt.CellStyle.Spacing.All = 1
rt.Rows(0).Style.TextAlignHorz = prt.AlignHorzEnum.Center
doc.Body.Children.Add(rt)
doc.Preview()

rt.Cells(0,Count).Text = Col.Name

 

改成

 

rt.Cells(0,Count).Text = Col.Caption

多层表头的导出，看看这里

谢谢袍哥

但是为什么后加的 插入的表达式列   这段在打印里面为什么显示不出来呢

With DataTables("日记账_Table1").DataCols '用表达式列计算库存数据
.Add("收入",Gettype(Double))
.Add("支出",Gettype(Double))
End With

For Each r As Row In Tables("日记账_Table1").Rows
Dim sum1 As Double = 0
Dim sum2 As Double =0
For Each c As Col In Tables("日记账_Table1").Cols
If c.Caption Like "*_收入*" Then
sum1 += r(c.name)
ElseIf c.Caption Like "*_支出*" Then
sum2 += r(c.name)
End If
Next
r("收入") = sum1
r("支出") = sum2
Next

 

 

 

18楼楼的代码，我测试没问题。先生成要打印的表，最后再写打印代码。
