Disable horizontal scroll for tables on mobiles

Hi!
I use kunena on my site.
When I open forum page on mobiles, it looks not very good and it displays message:

Scroll horizontally to view the whole table


But Kunena have own responsive styles and Kunena looks on mobiles not bad.

How to disable this mode for tables on mobiles?
Thanks.

Could you please post an url to your site - to a sample page where the change should be made?
