主题：竖表转水平表代码有问题

Dim tb As Table = Tables("标录分析_Table3")

Dim g As New GroupTableBuilder("统计表1", DataTables("开标记录B"))

g.Groups.AddDef("开标日期", DateGroupEnum.Year, "年")

g.Groups.AddDef("开标日期", "月")

g.Groups.AddDef("随机摸球法_中标球号")

g.Totals.AddDef("随机摸球法_中标球号", AggregateEnum.Count, "记录数")

g.GrandProportion = True

g.Filter = "[随机摸球法_中标球号] > 0"

tb.DataSource = g.BuildDataSource

tb.Sort = "年,月"

2、

Dim tb3 As Table = Tables("标录分析_Table3")

Dim tb4 As Table = Tables("标录分析_Table4")

Dim dtb As New DataTableBuilder("表B")

dtb.AddDef("年", Gettype(String), 32)

dtb.AddDef("月", Gettype(String), 32)

For Each nm As String In tb3.DataTable.GetValues("随机摸球法_中标球号")

    dtb.AddDef(nm, Gettype(Double))

Next

dtb.Build()

For Each nm As String() In tb3.DataTable.GetValues("年|月")

    Dim dr1 As DataRow = DataTables("表B").AddNew()

    dr1("年") = nm(0)

    dr1("月") = nm(1)

    For Each dr2 As DataRow In tb3.DataTable.Select("年 = '" & nm(0) & "' And 月 = '" & nm(1) & "'")

        dr1(dr2("随机摸球法_中标球号")) = dr2("记录数")

    Next

Next

tb4.DataSource = dtb.BuildDataSource
