主题：[求助]窗口筛选中如何加入交叉查询

窗口筛选中如何加入交叉查询？比如我想在表达式中加入如下查询命令，该怎么办？

想加入的交叉查询

Dim g As New CrossTableBuilder("统计表1", DataTables("2012年数据"))
g.Caption = "下属企业经营情况"
g.HGroups.AddDef("下属企业")
g.VGroups.AddDef("经营范围")
g.Totals.AddDef("项目编号", AggregateEnum.Count, "项目编号")
g.HorizontalTotal = True
g.VerticalTotal = True
g.Build()
MainTable = Tables("统计表1")

现有的表达式

Dim Filter As String
With e.Form.Controls("StartDate")
    If .Value IsNot Nothing Then
        If Filter >"" Then
            Filter = Filter & " And "
        End If
        Filter = Filter & "日期 >= #" & .Value & "#"
    End If
End With
With e.Form.Controls("EndDate")
    If .Value IsNot Nothing Then
        If Filter >"" Then
            Filter = Filter & " And "
        End If
        Filter = Filter & "日期 <= #" & .Value & "#"
    End If
End With
If Filter > "" Then
    Tables("2012年数据").Filter = Filter
End If
