如何通过在excel中使用结构化引用来获取表列的索引？

Question

I have a table with 3 columns. I want to write a formula that, given a structured reference, returns the index of the column. This will help me write VLookup formulas using the structured reference.

So, for example, for the table MyTable with columns A , B , C I'd like to be able to write:

=GetIndex(MyTable[C])

and have it return 3.

Right now I just make sure the table range starts on the sheet's first column and I write

=Column(MyTable[C])

but I want something a more robust.

Answer 1

A suitable formula based on your example would be

=COLUMN(MyTable[C])-COLUMN(MyTable)+1

The first part of the forumla COLUMN(MyTable[C]) will return the column number of the referenced column.

The second part of the formula COLUMN(MyTable) will always return the column number of the first column of the table.

Answer 2

Another solution to the question you asked (or something close to it) is to use something like =MATCH("C",MyTable[#Headers],0) , which will return 3 in the example you posted.

However, if you used INDEX instead of VLOOKUP, you wouldn't need to do this. For example, if you wanted to find the value of C in the row (assumingly there is no more than one) where A is equal to 2, you could use a formula like =INDEX(MyTable[C],MATCH(2,MyTable[A],0)) , which is nicely self-documenting.

Answer 3

Do you mean:

Dim r As Range
MyLetter ="AA"
Set r = Range(MyLetter & "1")
MyIndex= r.Column

Edit re comment

Function GetRelativeColumn(Letter, RangeName)
Dim r As Range
Dim ColStart, ColRequired, ColTemp
Set r = Range(RangeName)

ColStart = r.Column
ColRequired = Range(Letter & "1").Column
ColTemp = ColRequired - ColStart + 1
If ColTemp < 1 Or ColTemp > r.Columns.Count Then
    MsgBox "Ooutside range"
Else
    GetRelativeColumn = ColTemp
End If
End Function

Answer 4

=对eJames的响应稍作修改：= COLUMN（MyTable [*]） - MIN（COLUMN（MyTable））+ 1，其中*是您想要索引的列。

Answer 5

你可以使用： =COLUMN(MyTable[ * ]) - COLUMN(MyTable[A]) + 1 ，其中*是你想要的索引的列。

Answer 6

What is your end goal? You may be better off using SUMIF (as I describe here ) or INDEX (as I describe here ) to access your values rather than jumping back to row/column...
