Dim bd1 As New GroupTableBuilder("统计表1",DataTables("ruku"))

Dim dt1 As fxDataSource

bd1.Groups.AddDef("cid") '根据型号分组

bd1.Groups.AddDef("namex")

bd1.Groups.AddDef("storehouseid","rukuid")

bd1.Totals.AddDef("number","进货_数量") '对数量进行统计

bd1.Totals.AddDef("total","进货_金额") '对金额进行统计

dt1 = bd1.BuildDataSource()

Dim bd2 As New GroupTableBuilder("统计表2",DataTables("chuku"))

Dim dt2 As fxDataSource

bd2.Groups.AddDef("cid") '根据型号分组

bd2.Groups.AddDef("namex")

'bd2.Groups.AddDef("storehouseid","chukuid")

bd2.Totals.AddDef("number","销售_数量") '对数量进行统计

bd2.Totals.AddDef("total","销售_金额") '对金额进行统计

dt2 = bd2.BuildDataSource()

dt1.Combine("cid",dt2,"cid") '将销售统计数据组合到进货统计数据

Tables("ruku_Table1").DataSource = dt1 '将统计结果绑定到Table

With DataTables("ruku_Table1").DataCols '用表达式列计算库存数据

.Add("库存_数量",Gettype(Integer), "IsNull([进货_数量],0) - ISNULL([销售_数量],0)")

.Add("库存_金额",Gettype(Double), "[库存_数量] /[进货_数量] * [进货_金额]")

End With

'bd2.Groups.AddDef("storehouseid","chukuid")---一打开前头的注释就显示“已添加了具有相同键值的项”
