交叉统计生成的垂直分组列怎么让他降序排序啊？？

估计没有直接的方法。间接方法，就是生产统计表以后，动态调整列位置。

发错了

帖子发错地方了吧....

列名排序小例：

Dim t As Table = Tables("统计表1")
For i As Integer = 0 To t.Cols.Count - 1
    Dim k As Integer = i
    For j As Integer = i + 1 To t.Cols.Count - 1
        If t.Cols(i).Name < t.Cols(j).Name Then
            k = j
        End If
    Next   
    t.Cols(k).Move(i)
Next

呵呵，我也来个列明排序的:

 

Dim t As Table = Tables("表A")
Dim nms As new List(of String)
For Each c As col  In t.cols
    nms.add(c.name)
Next
nms.sort()
For i As Integer = 0 To nms.count -1
    t.cols(nms(i)).move(i)
Next

个人觉得这种排序还是不要去排，否则越排越乱。

交叉统计生成后的表，如果真要排序应该考虑分组列、合计列，如果有多个统计列还得考虑，否则结果是分组列和合计列不知跑到什么地方去，统计列会挤堆出现。

EXCEL里面的数据透视表也可以做交叉统计，它有个办法就是把垂直分组的那一列降序排序，不知道狐表是怎么弄的

自己编码，这样就可以排序：

做出来好多零怎么去掉？？

狐表代码计算出来的空结果总是带零，烦死了，强烈建议默认把零去掉
