OK, another newbie question. I have a table with columns of about 175 numbers (each of which is the sum of a bunch of stuff).
It is trivially easy to make each cell be an average... but I don't want that.
It is trivially easy to get a grand total on the column.
How do I get an average on the column?
(That is the total of all the values in the column divided by the number of rows in the table).
