I´ll try it, but can i add pictures in the table? how?

I copy this code in the quick css, but it doesn´t work. I use another element to get more than 5 columns, but i need to work with 7 colums in a specific page (I copy the link of the old web). It is a table with pictures.

Thank you ;)

Ok, Im working in local, so the web isnt online. But i have to re-design based on this (i copy the links down, there are two examples of the need to use more than five coloumns. Please in the second focus on the left middle zone where the icons are because i want to put them in horizontal position).

Thanks :)
