[Request] changing styles on the default theme

[orenmizr]

can the team show an example on how to change a style of a component correctly ? like table element for example.
it is unclear what is the source of truth - the scss ? the :root css vars ? and how to override correctly without masking style on top of another style.

does not have to be on the main branch - but i think there should be a reference example about the new.
much appreciated. 🙏
