Better configuration of Rich Text Table editing

Right now, editing tables is a bear. I almost always have to go into the code to fix them. Hubspot doesn’t use the proper TH heading structure. I would like to be able to add classes to my tables, change certain cells to TH and add a thead row at the top, things like this. It also seems to apply padding and other styles like width and height with no way to remove it except through html. Which is fine if you are familiar with HTML, but if you aren’t, it’s very frustrating.
