Oldschool…but useful for structured data and tabulation.
Is it possible as a feature?
There is nothing wrong with tables and are still as useful today as they were when invented.
The CSS guys younger than me would disagree…and I expect them to. It could potentially break their layout.
So I would say this would make for an amazingly specific plugin.
There was a discussion about adding CKEDITOR to discourse it was kind of a lighting rod subject and you can read it here.
While it is more that a, ‘can we add tables’ situation you can get a vibe on what html would do to mark up.
Hmm… I think I will let brighter minds chime in at this point.
Great topic for discussion as it is so specific.
