stuck in one-third

my theme keeps making the post table I created in a one-third, I can’t seem to find attributes for this in the style.css any idea where I could find this so that table is not placed in a third. I tried using a direct name in this plugin for the table but I guess it still writes out table prams when the page is viewed so its not bypassing css somewhere. any help would be greatly appreciated..thanks in advance..
