GrapeJS, MJML and tables not playing nice

Your software
My Mautic version is: 4.4.4

I am trying to create a table inside an MJML email, and it seems that each time I save it is stripping out all the tr th td tags. Anyone managed to build a table inside an MJML theme and can help with some code?

Oh this is a hard one.
You can always use
<mj-raw>WHATEVER TABLE<mj-raw>

As the GrapesJS will ignore anything between the tags.

I usually build tables with columns next to eachother, I find it better for display.
You can group columns together with <mj-group>
