excel - 比较两列并格式化具有不同颜色的匹配单元格

Question

感谢您在以下方面的帮助:

我想比较两列，让我们说 A 列和 B 列，**寻找重复项**。

如果 A 列中的值在 B 列中具有匹配值，我想用颜色格式化具有相同重复值的单元格(颜色是随机的并且每次匹配都不同)。

这是如果`A12 = B30`，颜色将为红色。如果`A20 = B1`，颜色是绿色等等。

如果没有匹配，就让它保持原样。

这只是红色和绿色的一个例子。假设您有两列(A 和 B)。

A1 = 1000

A2 = 2000

A3 = 3000

A4 = 4000

A5 = 5000

A6 = 6000

A7 = 7000

A8 = 8000

A9 = 9000

B1 = 1500

B2 = 9000

B3 = 5000

B4 = 3500

B5 = 7500

B6 = 1000

B7 = 4000

所以你有几场比赛，我需要每场比赛都是随机的不同颜色。例如:

A1 = B6 -> 它们将以绿色着色/突出显示

A4 = B7   –> 它们将被着色/以红色突出显示

A5 = B3 –> 它们将以黄色着色/突出显示

A9 = B2   –> 它们将以粉红色着色/突出显示

任何匹配的颜色都会不同，不匹配的颜色会减少或没有变化。

我希望这能解释这个问题，这必须使用 excel。

Sub UsingCollection()
Dim cUnique As Collection
Dim Rng As Range
Dim Cell As Range
Dim sh As Worksheet
Dim vNum As Variant for at
Dim LstRw As Long
Dim c As Range, clr As Long, x

Set sh = ActiveSheet
With sh

    LstRw = .Cells(.Rows.Count, "A").End(xlUp).Row
    Set Rng = .Range("A1:B" & LstRw)
    Set cUnique = New Collection
    Rng.Interior.ColorIndex = xlNone
    clr = 3

    On Error Resume Next
    For Each Cell In Rng.Cells
        cUnique.Add Cell.Value, CStr(Cell.Value)
    Next Cell
    On Error GoTo 0

    For Each vNum In cUnique

        For Each c In Rng.Cells
            If c = vNum Then
                x = Application.WorksheetFunction.CountIf(Rng, vNum)
                If x > 1 Then c.Interior.ColorIndex = clr "error here: the code runs fine for around 50 lines then it is stoppedand gives error and pointing to this line"
                  //Error shows in pop window: Run-time error 'g': Subscript out of range
            End If
        Next c
        clr = clr + 1
     Next vNum

   End With


End Sub

}

这是我在此处回答的调整后的代码。

遍历单元格以查找唯一值，然后遍历唯一值以对重复项着色。

Sub UsingCollection()
    Dim cUnique As Collection
    Dim Rng As Range
    Dim Cell As Range
    Dim sh As Worksheet
    Dim vNum As Variant
    Dim LstRw As Long
    Dim c As Range, clr As Long, x

    Set sh = ActiveSheet
    With sh

        LstRw = .Cells(.Rows.Count, "A").End(xlUp).Row
        Set Rng = .Range("A1:B" & LstRw)
        Set cUnique = New Collection
        Rng.Interior.ColorIndex = xlNone
        clr = 3

        On Error Resume Next
        For Each Cell In Rng.Cells
            cUnique.Add Cell.Value, CStr(Cell.Value)
        Next Cell
        On Error GoTo 0

        For Each vNum In cUnique

            For Each c In Rng.Cells
                If c = vNum Then
                    x = Application.WorksheetFunction.CountIf(Rng, vNum)
                    If x > 1 Then c.Interior.ColorIndex = clr
                End If
            Next c
            clr = clr + 1
        Next vNum

    End With

End Sub

结果

编辑:

使用 colorindex 将我们限制为 56 种颜色，如果我们使用 RGB，我们可以增加它。编辑这部分代码，您将不得不使用这些值来获得您喜欢的颜色变化。

       If x > 1 Then c.Interior.Color = 1000000 + clr * 100
            End If
        Next c
        clr = clr + 255
