我找到了为 3 列数据编写所有可能组合的脚本，但我正在尝试修改代码以编写 4 列，可能还有 5 列，但不确定如何。如果有人可以提供帮助，那就太好了！我已经尝试通过添加额外的变量来做我认为应该起作用的事情（我认为他们会在逻辑上进行），但是我得到了一个我无法解释的“编译错误：没有循环”。

这是来自 User Excelllll 的 3 列（未经我的修改）的代码。

代码的描述在这里：“此代码将从 A、B 和 C 列中获取数据，并给出您在 E、F 和 G 列中描述的输出。”

Sub combinations()

Dim c1() As Variant
Dim c2() As Variant
Dim c3() As Variant
Dim out() As Variant
Dim j, k, l, m As Long


Dim col1 As Range
Dim col2 As Range
Dim col3 As Range
Dim out1 As Range


Set col1 = Range("A1", Range("A1").End(xlDown))
Set col2 = Range("B1", Range("B1").End(xlDown))
Set col3 = Range("C1", Range("C1").End(xlDown))

c1 = col1
c2 = col2
c3 = col3

Set out1 = Range("E2", Range("G2").Offset(UBound(c1) * UBound(c2) * UBound(c3)))
out = out1

j = 1
k = 1
l = 1
m = 1


Do While j <= UBound(c1)
    Do While k <= UBound(c2)
        Do While l <= UBound(c3)
            out(m, 1) = c1(j, 1)
            out(m, 2) = c2(k, 1)
            out(m, 3) = c3(l, 1)
            m = m + 1
            l = l + 1
        Loop
        l = 1
        k = k + 1
    Loop
    k = 1
    j = j + 1
Loop


out1.Value = out
End Sub

在此先感谢您的帮助

这是一种通用方法，适用于任意数量的列/值（在合理范围内）。

示例用法：

Sub ListCombinations()

Dim col As New Collection
Dim c As Range, sht As Worksheet, res
Dim i As Long, arr, numCols As Long

    Set sht = ActiveSheet
   'lists begin in A1, B1, C1, D1
    For Each c In sht.Range("A1:D1").Cells
        col.Add Application.Transpose(sht.Range(c, sht.cells(Rows.Count, c.column).End(xlup))) 
        numCols = numCols + 1
    Next c
    
    res = Combine(col, "~~")
    
    For i = 0 To UBound(res)
        arr = Split(res(i), "~~")
        sht.Range("H1").Offset(i, 0).Resize(1, numCols) = arr
    Next i

End Sub

可重复使用的功能：

'create combinations from a collection of string arrays
Function Combine(col As Collection, SEP As String) As String()

    Dim rv() As String
    Dim pos() As Long, lengths() As Long, lbs() As Long, ubs() As Long
    Dim t As Long, i As Long, n As Long, ub As Long
    Dim numIn As Long, s As String, r As Long, v, tmp()

    numIn = col.Count
    ReDim pos(1 To numIn)
    ReDim lbs(1 To numIn)
    ReDim ubs(1 To numIn)
    ReDim lengths(1 To numIn)
    t = 0
    For i = 1 To numIn  'calculate # of combinations, and cache bounds/lengths
        'handle cases where only one value in a column (not passed in as array)
        If Not TypeName(col(i)) Like "*()" Then
            ReDim tmp(1 To 1)
            tmp(1) = col(i)
            col.Remove i
            If i > col.Count Then
                col.Add tmp
            Else
                col.Add tmp, before:=i
            End If
        End If
        lbs(i) = LBound(col(i))
        ubs(i) = UBound(col(i))
        lengths(i) = (ubs(i) - lbs(i)) + 1
        pos(i) = lbs(i)
        t = IIf(t = 0, lengths(i), t * lengths(i))
    Next i
    ReDim rv(0 To t - 1) 'resize destination array

    For n = 0 To (t - 1)
        s = ""
        For i = 1 To numIn
            s = s & IIf(Len(s) > 0, SEP, "") & col(i)(pos(i)) 'build the string
        Next i
        rv(n) = s

        For i = numIn To 1 Step -1
            If pos(i) <> ubs(i) Then   'Not done all of this array yet...
                pos(i) = pos(i) + 1    'Increment array index
                For r = i + 1 To numIn 'Reset all the indexes
                    pos(r) = lbs(r)    '   of the later arrays
                Next r
                Exit For
            End If
        Next i
    Next n

    Combine = rv
End Function

您可以尝试下面的代码来重新生成所有可能的组合（使用递归）

Public NextLevel As Integer

Private Sub CommandButton1_Click()
    NextLevel = 1
    Call rrd(1, ActiveSheet.Range("F5"), 1, "")
End Sub

Public Function rrd(initiator As Integer, lim As Integer, NextLeg As Integer,     CreatedComb) As Boolean

    If initiator = lim Then
      ActiveSheet.Range("G" & NextLevel) = CreatedComb & "," & initiator
      NextLevel = NextLevel + 1
    Else
      If NextLeg < lim Then
        ActiveSheet.Range("G" & NextLevel) = CreatedComb & "," & initiator
        NextLevel = NextLevel + 1
        Call rrd(initiator + 1, lim, initiator + 1, CreatedComb & "," & initiator)
      End If
      Call rrd(initiator + 1, lim, initiator, CreatedComb)
    End If

End Function
