Table Problems

Hi! I might need a coding solution to this, as I don’t think Royal Road’s setup plays nice with touch-tablets.

I’m trying to create a table for the character sheet for my story BUT I cannot seem to either split cells or merge cells. I can’t highlight them to do so. I’m working on a tablet, with a touchscreen, and various combinations of tapping just highlight the text WITHIN the cell, not a cell itself. Can’t highlight the cell, can’t merge or split the thing.

I tried copy-pasting between tables, and it just royally sporks the cell sizes for no reason I can see in the HTML. 

Any help would be GREATLY appreciated. 😭
