Simpler markup/markdown version #1
Description
Currently we have FormattedText which already has some markdown type features. The big test case for expanding this is how to represent columns and tables in such a format. we should look at CSS syntax for columns and Typst, Latex and GitHub markdown for tables. Additionally how builder functions would work needs to be investigated. One advantage of being able to do everything (or almost everything) in a markdown format is then we can add certain default styles such as default padding in certain places. Additionally a flatter (and simpler) structure is nicer to look at and work with than nested constructor calls for most people.
