Get the last column number of a search criteria in a defined range (if values are not unique)

问题

I have the following Excel spreadsheet:

   A      B                  C          D       E       F      G        H        I  
1     Search Criteria:    Prod.B
2     Column:               2
3                                   Prod.A   Prod.B  Prod.B  Prod.C   Prod.C   Prod.D
4                      
5      

Currently I use the following formula in Cell C2 to get the column of the search criteria in Cell C1 in the Range D3:I3.

=MATCH(C1,D3:H3,0)

All this works perfectly.

However, as you can see with the formula above I get back the first column number in which the search criteria appears.

What do I need to change in the formular to get the last column number in which the search criteria appears? (In the example above it would be 3)

回答1:

=MAX(IF(D3:I3=C1,COLUMN(D3:I3)-3))

Or:

=MATCH(2,1/(D3:I3=C1))

Enter both as array through CtrlShiftEnter

Alternatively:

=LOOKUP(2,1/(D3:I3=C1),COLUMN(D3:I3)-3)

It should still be an array formula but you don't have to enter it as such.
