Fixing columns in a table

I want to fix the percentages of columns in a table on the Radfighter theme. I know that this theme is HTML5 and therfore you cannot specify an exact pixel size but I need to have different tables with different number of columns used across the site.

 

Hello John,

I am not getting your issue. Please explain it little more.
But yes, If you are talking about columns on pages other then front page then you can use shortcodes.

Or

For tables you can use any table plugin.
