mysql - 使用交替颜色对 Excel 字段中的重复条目进行颜色编码

Question

我已经从 MySQL 数据库中提取了一个重复项列表到 Excel 工作表中。此 excel 显示我们有重复项(~1,900)，有时基于 excel 表的单个字段有三次条目。

例如:

10019
10019
10048
10048
10060
10060

我怎样才能为重复的对着色，以便它们可以很容易地可视化为每对的一对。基本上我想用交替的颜色填充每个重复的对，这样我就可以很容易地看到这些对。

您所说的过程称为“重复 strip ”。一对Scripting.Dictionary对象应该很容易处理这个问题。

Sub colorDuplicateColor2()
    Dim d As Long, dODDs As Object, dEVNs As Object, vTMPs As Variant
    Dim bOE As Boolean
    
    Set dODDs = CreateObject("Scripting.Dictionary")
    Set dEVNs = CreateObject("Scripting.Dictionary")
    dODDs.CompareMode = vbTextCompare
    dEVNs.CompareMode = vbTextCompare
    
    With Worksheets("Sheet7")
        If .AutoFilterMode Then .AutoFilterMode = False
        
        With .Range(.Cells(1, "C"), .Cells(Rows.Count, "C").End(xlUp))
            
            With .Columns(1)
                .Cells.Interior.Pattern = xlNone
            End With
            
            With .Resize(.Rows.Count - 1, 1).Offset(1, 0)
                vTMPs = .Value2
            End With
            
            For d = LBound(vTMPs, 1) To UBound(vTMPs, 1)
                'the dictionary Items have to be strings to be used as filter criteria
                If Not (dODDs.exists(vTMPs(d, 1)) Or dEVNs.exists(vTMPs(d, 1))) Then
                    If bOE Then
                        dODDs.Item(vTMPs(d, 1)) = CStr(vTMPs(d, 1))
                    Else
                        dEVNs.Item(vTMPs(d, 1)) = CStr(vTMPs(d, 1))
                    End If
                    bOE = Not bOE
                End If
            Next d
            
            With .Columns(1)
                .AutoFilter Field:=1, Criteria1:=dODDs.Items, Operator:=xlFilterValues
                .SpecialCells(xlCellTypeVisible).Interior.Color = RGB(210, 210, 210)
                'use this to band the entire row
                '.SpecialCells(xlCellTypeVisible).EntireRow.Interior.Color = RGB(210, 210, 210)
                'use this to band the row within the UsedRange
                'Intersect(.Parent.UsedRange, .SpecialCells(xlCellTypeVisible).EntireRow).Interior.Color = RGB(210, 210, 210)
                .AutoFilter
                .AutoFilter Field:=1, Criteria1:=dEVNs.Items, Operator:=xlFilterValues
                .SpecialCells(xlCellTypeVisible).Interior.Color = RGB(255, 200, 200)
                .Cells(1).EntireRow.Interior.Pattern = xlNone
            End With
            
        End With
        
        If .AutoFilterMode Then .AutoFilterMode = False
    End With
    
    dODDs.RemoveAll: Set dODDs = Nothing
    dEVNs.RemoveAll: Set dEVNs = Nothing
    Erase vTMPs

End Sub

当然，数据必须根据重复条件列进行排序。

这个过程可以很容易地针对整行或数据 block 内的行进行调整。
