Hi @LiteLotus, thanks for submitting this! I’m happy to see you submitted this as a feature request and not as a bug, as simple tables are quite new and work in progress in Anytype. The request is clear!
I mean at the end of they day if they want to graduate to PDF rendering they will mostelikely go the md route, which means they need to standardise. the best markdown to HTML renderer i know is remarkable and that uses GFM as its standard. by default things like LaTEX arent supported IIRC, but im sure there is a plugin for it, from there they can style the generated HTML with CSS and pipe that into a PDF rendrer, exposing stuff to the user if they really want. would be kinda cool to have a exposed css endpoint so we could style it but thats more wishfull thinking.
