Hueman Tables for Layouts

Please help!
I’ve done a nibbler website test and its saying the code quality is 0. They are giving me the following error.

All of the tested pages of this site appear to use tables for layout. This is very bad, as using tables for layout is not necessary and they should only contain tabular data.

Change this website to make use of div elements and CSS to create the desired layout. Only use tables for tabular data (e.g. a pricing table).

Does anyone know what to do? I love this theme and don’t want to change it.
