Re-reading your post, I have to wonder if you simply don't have the interface set up the way you're used to in CC2015. If the Properties window were missing, for example, it would lead someone to believe there are no options for size, font, or alignment. The properties window can be opened under Window > Properties, or Ctrl + F3. Once open, clicking the CSS button on the left will give you all the options you mentioned...
Inserting tables is available in a few places. Under Insert > HTML > Table or in the HTML tab of the Insert Window under Window > Insert. In my screenshot above, the Insert Window has been dragged to the top of the document window to dock as a toolbar (all those little icons). It's not normally there by default, so if you were used to those options being there, I could see how the program would feel very bare bones and almost code-only.
