电子表格函数中返回数组

下面的代码返回一个数组。我想在电子表格中使用它作为 Excel 公式来返回数组。但是，当我这样做时，它只将第一个值返回到单元格。无论如何，是否可以返回与数组大小相同的范围内的数组？

Function LoadNumbers(Low As Long, High As Long) As Long()
'''''''''''''''''''''''''''''''''''''''
' Returns an array of Longs, containing
' the numbers from Low to High. The
' number of elements in the returned
' array will vary depending on the
' values of Low and High.
''''''''''''''''''''''''''''''''''''''''

'''''''''''''''''''''''''''''''''''''''''
' Declare ResultArray as a dynamic array
' to be resized based on the values of
' Low and High.
'''''''''''''''''''''''''''''''''''''''''
Dim ResultArray() As Long
Dim Ndx As Long
Dim Val As Long
'''''''''''''''''''''''''''''''''''''''''
' Ensure Low <= High
'''''''''''''''''''''''''''''''''''''''''
If Low > High Then
    Exit Function
End If
'''''''''''''''''''''''''''''''''''''''''
' Resize the array
'''''''''''''''''''''''''''''''''''''''''
ReDim ResultArray(1 To (High - Low + 1))
''''''''''''''''''''''''''''''''''''''''
' Fill the array with values.
''''''''''''''''''''''''''''''''''''''''
Val = Low
For Ndx = LBound(ResultArray) To UBound(ResultArray)
    ResultArray(Ndx) = Val
    Val = Val + 1
Next Ndx
''''''''''''''''''''''''''''''''''''''''
' Return the array.
''''''''''''''''''''''''''''''''''''''''
LoadNumbers = ResultArray()

End Function

UDF 当然可以返回一个数组，并且您的函数可以正常工作。只需选择范围 B2:D2，然后输入=LoadNumbers(1, 3)进入编辑栏，然后按 Ctrl+Shift+Enter 告诉 Excel 这是一个数组函数。

现在，您无法让 UDF 自动调整范围大小它是从根据其输入（至少不是没有一些丑陋的Application.OnTimehack），但无论如何你都不需要这样做。只需将函数放在 1000 个单元格宽度的范围内，然后让 UDF 用空白单元格填充未使用的空间，如下所示：

Function LoadNumbers(ByVal Low As Long, ByVal High As Long) As Variant()
    Dim ResultArray() As Variant
    Dim Ndx As Long
    Dim Val As Long
    Dim SourceCols As Long

    SourceCols = Application.Caller.Columns.Count

    If Low > High Then
        Exit Function
    End If
    If High - Low + 1 > SourceCols Then High = Low + SourceCols - 1

    ReDim ResultArray(1 To SourceCols)

    Val = Low
    For Ndx = LBound(ResultArray) To (High - Low + 1)
        ResultArray(Ndx) = Val
        Val = Val + 1
    Next Ndx
    For Ndx = (High - Low + 2) To UBound(ResultArray)
        ResultArray(Ndx) = vbNullString
    Next Ndx
    LoadNumbers = ResultArray()
End Function
