主题：有条件的的选择显示冗余值

老师，请问下，我在高级筛选里选择显示冗余值，冗余值是在B列，A列是一串数字，我想判断的标准以A列里不是最大的数值提取出来

Dim idx As String = "-1,"
Dim idx_temp As String = ""
Dim pdr As DataRow = Nothing
Dim count As Integer = 0
Dim cs As String = "第二列"
For Each dr As DataRow In DataTables("表A").Select("", "第二列, 第一列 desc")
   
    Dim flag As Boolean = False
    If pdr IsNot Nothing Then
        For Each c As String In cs.split(",")
            If pdr(c) <> dr(c) Then
                flag = True
                Exit For
            End If
        Next
    End If
    If flag Then
        If count > 1 Then
            idx &= idx_temp
        End If
        count = 1
        idx_temp = ""
    Else
        count += 1
        idx_temp &= dr("_Identify") & ","
    End If
   
    pdr = dr
Next

If count > 1 Then
    idx &= idx_temp
End If

Tables("表A").filter = "_Identify in (" & idx.trim(",") & ")"

老师，用代码检测了下会显示出1.2.3.5这四行，我是想达到这样的效果，比如选A时，会显示出1.2行，因为3最大，选B时，显示4因为5比4大

代码我测试没问题。如果有问题发例子上来测试。
