excel:如何在单元格内排序？

Question

我有一个用逗号分隔的字符串，是否可以使用 Excel 公式对单元格内的值进行排序？

Answer 1

这是一个解决方案(从 here 窃取的快速排序代码)。您只需将一个按钮连接到 SortVals 宏，然后只需单击该按钮，它就会对事件单元格中的逗号分隔值进行排序。

Option Explicit

Public Sub SortVals()
    Dim i As Integer
    Dim arr As Variant
    arr = Split(ActiveCell.Text, ",")

    ' trim values so sort will work properly
    For i = LBound(arr) To UBound(arr)
        arr(i) = Trim(arr(i))
    Next i

    ' sort
    QuickSort arr, LBound(arr), UBound(arr)

    ' load sorted values back to cell
    Dim comma As String
    comma = ""
    ActiveCell = ""
    For i = LBound(arr) To UBound(arr)
        ActiveCell = ActiveCell & comma & CStr(arr(i))
        comma = ","
    Next i
End Sub

Public Sub QuickSort(vArray As Variant, inLow As Long, inHi As Long)

  Dim pivot   As Variant
  Dim tmpSwap As Variant
  Dim tmpLow  As Long
  Dim tmpHi   As Long

  tmpLow = inLow
  tmpHi = inHi

  pivot = vArray((inLow + inHi) \ 2)

  While (tmpLow <= tmpHi)

     While (vArray(tmpLow) < pivot And tmpLow < inHi)
        tmpLow = tmpLow + 1
     Wend

     While (pivot < vArray(tmpHi) And tmpHi > inLow)
        tmpHi = tmpHi - 1
     Wend

     If (tmpLow <= tmpHi) Then
        tmpSwap = vArray(tmpLow)
        vArray(tmpLow) = vArray(tmpHi)
        vArray(tmpHi) = tmpSwap
        tmpLow = tmpLow + 1
        tmpHi = tmpHi - 1
     End If

  Wend

  If (inLow < tmpHi) Then QuickSort vArray, inLow, tmpHi
  If (tmpLow < inHi) Then QuickSort vArray, tmpLow, inHi

End Sub
