Is your feature request related to a problem? Please describe.
Currently there does not appear to be a way to create or edit table elements through the interface.

Describe the solution you'd like
Add Tables to list of available Block Components along with controls to add/remove rows and columns to existing table elements.

Describe alternatives you've considered
Creating/editing tables has to be done using the Text editor or switching to WordPress/Gutenberg to add and manage the element.
