Graphics, Figures & Tables ⇒ Too many columns for page width

[Monkey D]

I have a table with 22 columns, which is too much for a page in portrait setting. In fact it's a table with 22 columns and 22 rows, but the problem is with the number of columns.
I can barely fit the table in landscape with footnotesize font, and would like to find a better way.

My tables are generated with csv2latex, so I would like to break columns in an to be automatic.

Isn't there anything like a "\columnbreak{10}" command to break rows at every 10th row?

Thanks
