Dim b As New GroupTableBuilder("统计表","表1")

Dim dt As fxDataSource

b.Groups.AddDef("部门名称")

b.Totals.AddDef("金额","销售金额")

dt = b.BuildDataSource()

Dim b1 As New SQLCrossTableBuilder("统计表1","表2")

Dim dt1 As fxDataSource

b1.HGroups.AddDef("部门名称")

b1.VGroups.AddDef("成本大类")‘此处的成本大类名称可能会随时调整，

b1.Totals.AddDef("金额")

dt1 = b1.BuildDataSource()

上面“表2”的成本大类的名称可能会随时改变，导致交叉统计的列名称和列数都不固定，我需要计算b1各个成本大类占b中的销售的比率，由于列名称和列数不固定，用下面这种方法好象也处理不了，有没有其他办法解决呢

Dim dic As new Dictionary(of String, String)

For Each c As Col In Tables("汇总表_Table1").cols

dic.add(c.Caption, c.name)

If dic.ContainsKey("销售金额") = False Then

DataTables("汇总表_Table1").dataCols.add("销售金额", Gettype(Double))

dic.add("销售金额", "销售金额")

End If

知道怎么解决了

以交叉统计的形式，统计每个客户订购不同产品的数量和金额：

Dim dtb As New DataTableBuilder("统计")
dtb.AddDef("客户", Gettype(String), 16)
Dim prds As List(of String) = DataTables("订单").GetValues("产品")
For Each prd As String In prds
    dtb.AddDef(prd & "_数量", Gettype(Integer))
    dtb.AddDef(prd & "_金额", Gettype(Double))
Next
dtb.Build()
For Each cus As String In DataTables("订单").GetValues("客户")
    Dim dr As DataRow = DataTables("统计").AddNew()
    dr("客户") = cus
    For Each prd As String In prds
        dr(prd & "_数量") = DataTables("订单").Compute("Sum(数量)","客户 = '" & cus & "' And [产品] = '" & prd & "'")
        dr(prd & "_金额") = DataTables("订单").Compute("Sum(金额)","客户 = '" & cus & "' And [产品] = '" & prd & "'")
    Next
Next
MainTable= Tables("统计")

Dim r1 As Row

For i As Integer = 0 To t1.Rows.Count(True) - 1

r1 = t1.Rows(i,True)

For Each prd As String In prds

Dim xs As Double = DataTables("费用构成情况_Table1").Compute("Sum(销售金额)","部门名称 = '" & r1("部门名称") & "' And " & HZ3 & " = '" & prd & "'")

If r1.IsGroup And xs <> 0 Then

r1(prd & "_销售占比") = DataTables("费用构成情况_Table1").Compute("Sum(费用金额)","部门名称 = '" & r1("部门名称") & "' And " & HZ3 & " = '" & prd & "'")/DataTables("费用构成情况_Table1").Compute("Sum(销售金额)","部门名称 = '" & r1("部门名称") & "' And " & HZ3 & " = '" & prd & "'")

ElseIf r1.IsGroup And xs = 0 Then

r1(prd & "_销售占比") =0

End If

上面标红部分，汇总行的计算代码不对，应该怎么调整

For i As Integer = 0 To t1.Rows.Count(True) - 1

r1 = t1.Rows(i,True)

msgbo(r1("部门名称"))这里显示什么内容？汇总后部门名称列的数据是怎么样的？截图看看

不知咋回事，上传不了图，根据提示，汇总行计算中，" & HZ3 & " = '" & prd & "'这里不对，提示未找到列

多上传几次：http://www.foxtable.com/bbs/dispbbs.asp?boardid=2&Id=78

msgbox("部门名称 = '" & r1("部门名称") & "' And " & HZ3 & " = '" & prd & "'") 显示什么内容？

唉，解决了，是自己想多了

Dim r1 As Row

For i As Integer = 0 To t1.Rows.Count(True) - 1

r1 = t1.Rows(i,True)

For Each prd As String In prds

If r1.IsGroup Then

If r1("销售金额") <> 0 Then

r1(prd & "_销售占比") = r1(prd & "_费用金额")/r1("销售金额")

ElseIf r1("销售金额") = 0 Then

r1(prd & "_销售占比") =0

End If
