How to implement Tables in Gantry 5

Hello dear Grav Community,

I use gantry 5 plugin and the datatables Plugin. The datatable Plugin works fine and he creates my tables here an example:

"

Firma Name Zeit Sitzungszimmer
Test AG Denis Denis 11:30 Titlis 3.OG
Firma AG Dominique Dominique 12:00 Rigi 2.OG
"

But he don’t intepret my html and the sites looks like this:

Do I miss something ?

Thanks for the time !

Could you post the Twig where your table is generated from?
