如何在excel中对列表进行分组？

VBA 宏可以生成结果，以及第一列结果的参数列表。

要输入此宏 (Sub)，请alt-F11打开 Visual Basic 编辑器。确保您的项目在“项目浏览器”窗口中突出显示。然后，从顶部菜单中，选择插入/模块并将下面的代码粘贴到打开的窗口中。

请务必按照宏中注释中的说明设置参考

要使用此宏 (Sub)，请alt-F8打开宏对话框。按名称选择宏，然后RUN。

此宏使用第一列中的参数列表生成列表。如果更可取，可以轻松地将参数列表重写为第一行。

Option Explicit
'Set Reference to Microsoft Scripting Runtime

Sub GroupLists()
    Dim wsSrc As Worksheet, wsRes As Worksheet, rRes As Range
    Dim vSrc As Variant, vRes As Variant
    Dim dictParams As Dictionary
    Dim sParam As String
    Dim I As Long, J As Long, K As Long
    Dim V As Variant

Set wsSrc = Worksheets("sheet1")
Set wsRes = Worksheets("sheet1")
    Set rRes = wsRes.Cells(1, 5)

With wsSrc
    vSrc = .Range(.Cells(1, 1), .Cells(.Rows.Count, 1).End(xlUp)).Resize(columnsize:=2)
End With

'Get unique list of Parameters with row number
'Also count the number of entries for number of columns in final result
J = 0
Set dictParams = New Dictionary
K = 0 'row number for parameter
For I = 1 To UBound(vSrc, 1)
    J = J + 1 'column count
    Do
        If Not dictParams.Exists(vSrc(I, 1)) Then
            K = K + 1
            dictParams.Add Key:=vSrc(I, 1), Item:=K
        End If
        I = I + 1
        If I > UBound(vSrc) Then Exit Do
    Loop Until vSrc(I, 1) = ""

    If I > UBound(vSrc) Then Exit For
Next I

'Create results array
ReDim vRes(1 To dictParams.Count, 1 To J + 1)

'Populate Column 1
For Each V In dictParams.Keys
    vRes(dictParams(V), 1) = V
Next V

'Populate the data
J = 1 'column number
For I = 1 To UBound(vSrc, 1)
    J = J + 1
    Do
        sParam = vSrc(I, 1)
        vRes(dictParams(sParam), J) = vSrc(I, 2)
        I = I + 1
        If I > UBound(vSrc) Then Exit Do
    Loop Until vSrc(I, 1) = ""

    If I > UBound(vSrc) Then Exit For
Next I

'Write the results
Set rRes = rRes.Resize(UBound(vRes, 1), UBound(vRes, 2))
rRes.EntireColumn.Clear
rRes = vRes

End Sub

编辑：修改宏以反映“真实数据”

请注意：您需要为结果添加第二个工作表。我将其命名为“Sheet2”

Option Explicit
'Set Reference to Microsoft Scripting Runtime

Sub GroupLists()
    Dim wsSrc As Worksheet, wsRes As Worksheet, rRes As Range
    Dim vSrc As Variant, vRes As Variant
    Dim dictParams As Dictionary
    Dim sParam As String
    Dim I As Long, J As Long, K As Long
    Dim V As Variant
    Dim sDelim As String 'Differentiates each record

Set wsSrc = Worksheets("sheet1")
Set wsRes = Worksheets("sheet2")
    Set rRes = wsRes.Cells(1, 1)

With wsSrc
    vSrc = .Range(.Cells(1, 1), .Cells(.Rows.Count, 1).End(xlUp)).Resize(columnsize:=2)
    sDelim = vSrc(1, 1)
End With

'Get unique list of Parameters with row number
'Also count the number of entries for number of columns in final result

Set dictParams = New Dictionary

For I = 1 To UBound(vSrc, 1)
    J = J + 1 'column count
    Do
        If Not dictParams.Exists(vSrc(I, 1)) Then
            K = K + 1
            dictParams.Add Key:=vSrc(I, 1), Item:=K
        End If
        I = I + 1
        If I > UBound(vSrc) Then Exit Do
    Loop Until vSrc(I, 1) = sDelim

    If I > UBound(vSrc) Then
        Exit For
    Else
        I = I - 1
    End If
Next I

'Create results array
ReDim vRes(1 To dictParams.Count, 1 To J + 1)

'Populate Column 1
For Each V In dictParams.Keys
    vRes(dictParams(V), 1) = V
Next V

'Populate the data
J = 1 'column number
For I = 1 To UBound(vSrc, 1)
    J = J + 1
    Do
        sParam = vSrc(I, 1)
        vRes(dictParams(sParam), J) = vSrc(I, 2)
        I = I + 1
        If I > UBound(vSrc) Then Exit Do
    Loop Until vSrc(I, 1) = sDelim

    If I > UBound(vSrc) Then
        Exit For
    Else
        I = I - 1
    End If
Next I

'Write the results
Set rRes = rRes.Resize(UBound(vRes, 1), UBound(vRes, 2))
rRes.EntireColumn.Clear
rRes = vRes

End Sub

EDIT2：这个宏是对上面的修改，它列出了相反方向的结果。它可能更有用。
