VOOK宏錯誤與VLOOKUP一起使用

Question

我最近使用了來自@LondonRob的帖子中的代碼，它允許在使用VLOOKUP時將包含數據的單元格格式轉移。

原始問題 - 復制單元格顏色的Vlookup - Excel VBA

這很好，適用於大多數價值觀。 不幸的是，有些值無法傳輸格式，我收到錯誤：

運行時錯誤“13”：數據不匹配

我已經取出所有空單元格並通過反復試驗取出任何公式錯誤並糾正錯誤拼寫。 嘗試運行宏時，仍然有一些單元格會顯示此消息。

我看不到數據中的任何錯誤，並且單元格中出現此錯誤似乎幾乎是隨機的。 數據集也很龐大，因此即使找到所有有問題的單元也很難（我找到了一些）。

我會評論這個帖子，但我現在還沒有聲譽。

使用的編碼是（雖然在我的模塊中我拿出前6行） -

Answer 1

那里有很多代碼，所以很難說確切的問題是什么。

試試這個版本：

Sub tester()
    Dim c As Range
    If TypeName(Selection)<>"Range" Then Exit Sub
    For Each c In Selection
        CopySourceFormats c
    Next c
End Sub


'If the passed cell has a VLOOKUP formula,
'  extract the arguments and find the source of the return value.
'Copy formatting from that cell to the cell with the formula
Sub CopySourceFormats(c As Range)
    Dim arr, v, rng As Range, col As Long, f As String
    Dim m, fs As Font, fd As Font, rngSrc As Range

    'skip any unwanted cells
    f = c.Formula
    If Not f Like "=VLOOKUP(*" Then Exit Sub
    If IsError(c.Value) Then Exit Sub 'no "source" cell to find



    'Extract just the arguments and create an array 
    '  (assumes no arguments contain a comma: 
    '  would need better parsing otherwise)
    f = Replace(f, "=VLOOKUP(", "")
    f = Left(f, Len(f) - 1)
    arr = Split(f, ",")

    v = c.Parent.Evaluate(arr(0)) 'get lookup value
    Set rng = Evaluate(arr(1))    'source table (could be on another sheet)
    col = CLng(arr(2))            'column number in lookup table

    'Debug.Print v, rng.Address(), col

    'Try to match the value in the first column of the lookup table
    m = Application.Match(v, rng.Columns(1), 0)

    'Got a match? Copy formatting for the "source" cell
    If Not IsError(m) Then
        Set rngSrc = rng.Cells(m, col)
        Set fs = rngSrc.Font
        Set fd = c.Font
        'copy formatting: add/subtract properties to suit...
        fd.Size = fs.Size
        fd.Color = fs.Color
        fd.Bold = fs.Bold
        c.Interior.ColorIndex = rngSrc.Interior.ColorIndex
    End If
End Sub
