Look inside table

This software displays a small part of a (very) big table. Compared to Look inside file, Look inside table is better to explore a table but will use more memory because one whole line is loaded into memory ;)

The table slice is printed on the screen and in a file.

Enjoy ;)

Caution : The end of line used by this software is Unix like : \n. It has been tested only with Unix like files (end of line \n), it should work with windows files (end of line \r\n) and it should not work with Apple files (end of line \r). File conversion is possible with search replace word (see convert Mac or Win file into Unix).
