I have about 2000 rows and 30 columns, each row does not always contain data
in the same column. My neck will be safe if I can identify the maximum amount
of rows sharing the same columns with data. So I could say, for example, that
184 rows had -at least- data in column 5, 8, 13, 16, 17 and 25. It is
possible that several rows in the selection have data in more columns.
I really would be grateful for any help.
