主题：问下分组汇总

呵呵，做个简单的例子说话吧。

你漏掉了一行代码：

Dim t As Table = Tables("订单")
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 = "客户"
g.TotalOn = "数量"
g.Caption = "{0} 小计"
t.SubtotalGroups.Add(g)

g = New Subtotalgroup
g.Aggregate = AggregateEnum.Sum
g.GroupOn = "*"
g.TotalOn = "数量"
g.Caption = "总计"
t.SubtotalGroups.Add(g)
t.Subtotal()
