Border on tables?

Hello,

When I put a table into the site, it shows a thin border even if I set the border to "0" in the table settings. Is there a automatic border that I can turn off using the styling options?

I have a table for the social media stuff and a table for the testimonials at the bottom. Both on the front page.

Hello,

Paste this code in Custom CSS
Appearance > Theme Option > Styling Option > Custom CSS

Code:

td, th {
border: none!important;
}
