参考

 

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

If count > 1 Then
    idx &= idx_temp
End If

\'Tables("表A").filter = "_Identify not In (" & idx.trim(",") & ")"
Tables("表A").filter = "_Identify In (" & idx.trim(",") & ")"

可不可以实现显示重复值，例如姓名，身份账号，将同名同号的列出来

Tables("表A").RepeatFilter("第一列", 0)

Tables("表A").RepeatFilter("第二列", 0)

就像这个功能差不多，第一列+第二列的值，但只是显示出来
