HTML Elements get cut off

I was planning on using Tableberg for my small wiki page that relies on some unique designed html elements in the table.
When I add the HTML to the table it looks fine in the preview, but as soon as I publish it the elements get cut off in the table. You can have a look at our current test site I linked.

With the custom made table at the bottom of the site https://forzawiki.com/wiki/autos/ the elements are shown the right way.

I’m using the Astra theme, but the issue also occurs with other themes.
