主题：[求助]如何取消总计分组?

Dim t As Table = Tables(bm4)

Dim g As Subtotalgroup

t.SubtotalGroups.Clear()

'定义总计分组

g = New Subtotalgroup

g.Aggregate = AggregateEnum.Sum

g.GroupOn = "*" '注意总计分组用符号*表示.

g.TotalOn = "数量,小计"

g.Caption = "总计"

t.SubtotalGroups.Add(g)

t.Subtotal() '生成汇总模式

按上述码形成汇总之后,使用

Dim t As Table = Tables(bm4)

Dim g As Subtotalgroup

t.SubtotalGroups.Clear()

怎么取消不了汇总呢?谢谢
