Excel VLOOKUP函数源代码

Question

无论如何我可以在excel（VBA）中找到函数VLOOKUP的源代码，以便我可以修改它吗？谷歌没有给我任何帮助。谢谢！

Answer 1

Excel / VBA不是开源的，因此特定功能的源代码不可用。

您可以在VBA中编写自己的UDF（用户定义函数）以生成修改后的版本。

还有一个更灵活（非VBA）版本的VLOOKUP / HLOOKUP

Answer 2

基于Vahid的回答，这对我不起作用，我做了以下代码，但是它确实有效：

Function CUSTOMVLOOKUP(lookup_value As String, table_array As Range, col_index_num As Integer)
    Dim i As Long
    For i = 1 To table_array.Rows.Count
        If lookup_value = table_array.Cells(i, 1) Then
            CUSTOMVLOOKUP = table_array.Cells(i, col_index_num)
            Exit For
        End If
    Next i
End Function

Answer 3

这是Vlookup的简单实现：

        Public Function VLOOKUP1(ByVal lookup_value As String, ByVal table_array As Range, ByVal col_index_num As Integer) As String
        Dim i As Long

        For i = 1 To table_array.Rows.Count
            If lookup_value = table_array.Cells(table_array.Row + i - 1, 1) Then
                VLOOKUP1 = table_array.Cells(table_array.Row + i - 1, col_index_num)
                Exit For
            End If
        Next i

        End Function
