Proposition: tables

[eddow]

I see tables are not yet implemented in sveltemantic and I have a proposition.

I am making a column-wise table definition for svelte who has no styling yet. If it is considered valuable, it could be either referenced by sveltemantic and maintained for it or c/p-ed in sveltemantic source.

In the former case, it would of course be maintained (by me or other PR) to fit sveltemantic policies.

I already used that principle in v-semantic (semantic for vue) - indeed with even a bit more of abstraction
