The table below calculates the composite rankings of the teams in the NFC playoffs based on the averages of several different rankings. My formula in the Ave column uses literal column addresses. If I find another ranking (Rtg4) and add a new column, I have to edit the formula.

D6:D12D6=RANK.EQ([@Ave],[Ave],1)
E6:E12E6=AVERAGE([@Rtg1]:[@Rtg3])


In this table, I added a dummy last column so I could use Offset for an average formula that automatically adjusts for any new columns. Is there a better way that does not need a dummy column?

Excel Facts

Return population for a City
If you have a list of cities in A2:A100, use Data, Geography. Then =A2.Population and copy down.
How about
Excel Formula:
=AVERAGE(DROP(Table1[@],,XMATCH(Table1[[#Headers],[Ave]],Table1[#Headers])))
Change the table name to suit.

The Drop function in your example drops the first 4 columns from the table. Is there a slightly different formula that drops the first n and the last m columns in a table? Or is there an Include or Keep function that will keep a variable number of columns in the middle of a table?

You can replace the xmatch function with a the number of columns you want to drop from the start of the table & wrap it in another DROP where you can give it a -ve number to drop the last m columns.

If all your rating columns start with Rtg couldn't you just use:

Excel Formula:
=AVERAGEIF(Table1[#Headers],"Rtg*",Table1[@])
