主题：[求助]高亮显示重复数据

Dim idx As String = ""
Dim idx_temp As String = ""
Dim pdr As DataRow = Nothing '这行代码是指表中哪一行?
Dim count As Integer = 0
For Each dr As DataRow In DataTables("表A").Select("日期时间 is not null", "姓名,日期时间")
    output.show(dr("姓名") & dr("日期时间"))
    If pdr IsNot Nothing AndAlso (pdr("日期时间").Date <> dr("日期时间").Date OrElse pdr("姓名") <> dr("姓名")) Then
        output.show(count)
        If count > 2 Then
            idx &= idx_temp
        End If
        count = 1
        idx_temp = ""
    Else
        count += 1
    End If
    idx_temp &= dr("_Identify") & ","
    pdr = dr
Next

If count > 2 Then
    idx &= idx_temp
End If

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

 pdr 是指上一行。这种用法在Foxtable中没见着呀?还是不理解,请老师详细介绍一下.
