Drawing Tables in 2017

Has anybody else noticed any strange Table behavior in SW2017?

I have a lot of trouble inserting new columns into tables. I can do it once maybe if i am lucky, but then I have to restart SW in order to get the Right-Click "Insert" menu item to re-appear. Of course there's always the possibility that I'm going bonkers.

Thanks

Marshall
