根据帖子《如何标注出多列内容相同的行》（链接http://www.foxtable.com/bbs/dispbbs.asp?BoardID=2&ID=114307&skin=0）中有点甜老师给予的删除重复代码稍作修改，在删除重复合同编号时，多删除了序号8、合同编号为2016GTE01，不知道问题出在哪里，请老师赐教。

改成这样

Dim idx As String = "-1,"
Dim idx_temp As String = ""
Dim pdr As DataRow = Nothing
Dim count As Integer = 0
Dim cs As String = "合同编号"
For Each dr As DataRow In DataTables("去重复合同编号").Select("", "合同编号")
   
    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 OrElse pdr Is Nothing 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("去重复合同编号").filter = "_Identify in (" & idx.trim(",") & ")"

\'Tables("去重复合同编号").filter = "_Identify not in (" & idx.trim(",") & ")"  \'显示唯一值
