主题：如何将每个分组加个合计

生成统计之后，再设置汇总模式，不就好了？如代码

Dim t As Table = Tables("窗口1_Table1")
Dim g As SubtotalGroup
t.SubtotalGroups.Clear()
t.GroupAboveData = False
t.TreeVisible = False
t.SpillNode = True

g = New SubtotalGroup
g.Aggregate = AggregateEnum.Sum
g.GroupOn = "四级科目"
g.TotalOn = "预算下达_金额,实际支付_金额,收支_结余"
g.Caption = "{0} 小计"
t.SubtotalGroups.Add(g)

g = New SubtotalGroup
g.Aggregate = AggregateEnum.Sum
g.GroupOn = "*"
g.TotalOn = "预算下达_金额,实际支付_金额,收支_结余"
g.Caption = "总计"
t.SubtotalGroups.Add(g)

t.Subtotal()

这个意思？

汇总统计的话，只能这样了

Dim t As Table = Tables("窗口1_Table1")
Dim g As Subtotalgroup
t.SubtotalGroups.Clear()
t.GroupAboveData = False
t.TreeVisible = False
t.SpillNode = False

g = New Subtotalgroup
g.Aggregate = AggregateEnum.Sum
g.GroupOn = "四级科目"
g.TotalOn = "预算下达_金额,实际支付_金额,收支_结余"
g.Caption = "{0} 小计"
t.SubtotalGroups.Add(g)

g = New Subtotalgroup
g.Aggregate = AggregateEnum.Sum
g.GroupOn = "三级科目"
g.TotalOn = "预算下达_金额,实际支付_金额,收支_结余"
g.Caption = "{0} 小计"
t.SubtotalGroups.Add(g)

g = New Subtotalgroup
g.Aggregate = AggregateEnum.Sum
g.GroupOn = "二级科目"
g.TotalOn = "预算下达_金额,实际支付_金额,收支_结余"
g.Caption = "{0} 小计"
t.SubtotalGroups.Add(g)

g = New Subtotalgroup
g.Aggregate = AggregateEnum.Sum
g.GroupOn = "一级科目"
g.TotalOn = "预算下达_金额,实际支付_金额,收支_结余"
g.Caption = "{0} 小计"
t.SubtotalGroups.Add(g)

t.Subtotal()

For i As Integer = 0 To t.Rows.count(True)-1
    Dim r As Row = t.Rows(i, True)
    If r.IsGroup Then
        r("资金来源") = Nothing
        If r.Level = 0 Then
            r("一级科目") = "总计"
        ElseIf r.Level = 1 Then
            r("二级科目") = "合计"
        ElseIf r.Level = 2 Then
            r("三级科目") = "合计"
        ElseIf r.Level = 3 Then
            r("四级科目") = "小计"
        End If
    End If
Next

 或者，这样写

Dim bd1 As New GroupTableBuilder("统计表1",DataTables("预算统计表"))
Dim dt1 As fxDataSource
bd1.Groups.AddDef("资金来源") '根据型号分组
bd1.Groups.AddDef("预算资金性质") '根据型号分组

bd1.Totals.AddDef("预算下达金额","预算下达_金额")  '对数量进行统计
dt1 = bd1.BuildDataSource()
