I think my main issue with tables on WYSIWYG editors is that they are easy to create but become very difficult to manage. For example, you create a 2x3 table, but later want to add an additional column.
☒ I would probably use their provided gem for bootstrap. But for other things where a gem isn't provided, I am not quite sure of the best method yet. I think that this will be one of the growing pains as we'd have to find out the best routes for these things. I can see other libraries like FullCalendar where this too would be a concern.
