Table block: missing row types (header and footer)

[benoitchantre]

Version tested: Gutenberg 1.7

Issue Overview

We can already create and modify a table, but unless we edit HTML directly, there's no way to have a header or a footer for the table. The first row of a table usually contains the titles of the columns and should be described and styled as a header.

Expected Behavior

As a user, I would like to be able to change the type of row (header, body or footer) from the table dropdown. Rows inside <thead> should have a slightly different style.

I am moving this to ideas as it would be an extra feature that feels out of scope for version one but absolutely could be good to add later. We're keeping issues closed but in that project as a log while we work on the release.
