I want to make a croos section between two columns on a third column.
Actualy, I have two colums, first one containing a lists of numbers from 1 to
2000 and a second column with 700 numbers from the same range (i.e. 1, 4 ,17,
22, 23 ...). I need a third column that has the difference of 1300 numbers
that do not appear in the second column.
Thanks
