Using Custom CSS

Hi. i came across a website which lets you create table. The tables created by that site are pretty good especially for affiliate sites. Porblem is , these type of sites don’t last much longer and will get disappear from the internet. Site already has already given CSS, so is their any way to integrate that table theme in Tablepress plugin. Thank You.
