反透视数据 table 并为每个具有值 (VBA) 的单元格返回列 header 值

Question

我正在处理一个包含许多列的数据集，这些列并非都具有关联值。我已经能够找到一些 VBA 代码来对每一行的数据进行反透视并捕获固定字段。但是，列的 header 包含有关关联值的特定信息。我需要帮助返回每个识别了值的字段的列标题值。

所需输出（仅缺少 Header/“帐户”值

当前VBA我正在使用

Sub Tester()
    
    Dim p
    
    'get the unpivoted data as a 2-D array
    p = UnPivotData(Sheets("Sheet1").Range("A1").CurrentRegion, _
                  6, False, False)
                
    With Sheets("Sheet2").Range("A1")
        .CurrentRegion.ClearContents
        .Resize(UBound(p, 1), UBound(p, 2)).Value = p 'populate array to sheet
    End With

End Sub

Function UnPivotData(rngSrc As Range, fixedCols As Long, _
                   Optional AddCategoryColumn As Boolean = True, _
                   Optional IncludeBlanks As Boolean = True)

    Dim nR As Long, nC As Long, data, dOut()
    Dim r As Long, c As Long, rOut As Long, cOut As Long, cat As Long
    Dim outRows As Long, outCols As Long
    
    data = rngSrc.Value 'get the whole table as a 2-D array
    nR = UBound(data, 1) 'how many rows
    nC = UBound(data, 2) 'how many cols

    'calculate the size of the final unpivoted table
    outRows = nR * (nC - fixedCols)
    outCols = fixedCols + IIf(AddCategoryColumn, 2, 1)
    
    'resize the output array
    ReDim dOut(1 To outRows, 1 To outCols)
               
    'populate the header row
    For c = 1 To fixedCols
        dOut(1, c) = data(1, c)
    Next c
    If AddCategoryColumn Then
        dOut(1, fixedCols + 1) = "Category"
        dOut(1, fixedCols + 2) = "Value"
    Else
        dOut(1, fixedCols + 1) = "Value"
    End If

    
    'populate the data
    rOut = 1
    For r = 2 To nR
        For cat = fixedCols + 1 To nC
            
            If IncludeBlanks Or Len(data(r, cat)) > 0 Then
                rOut = rOut + 1
                'Fixed columns...
                For c = 1 To fixedCols
                    dOut(rOut, c) = data(r, c)
                Next c
                'populate unpivoted values
                If AddCategoryColumn Then
                    dOut(rOut, fixedCols + 1) = data(1, cat)
                    dOut(rOut, fixedCols + 2) = data(r, cat)
                Else
                    dOut(rOut, fixedCols + 1) = data(r, cat)
                End If
            End If
        Next cat
    Next r
    
    UnPivotData = dOut
End Function

Answer 1

UnPivotData 有一个参数 AddCategoryColumn，您要将 False 传递给该参数 - 如果您改为传递 True，那么您将获得想要的结果。
