Duh, still no table tool. Every basic HTML editor has this ****. I'll be sticking with OneNote.
I think that is because Notability was designed primarily as a handwritten note taking tool with the stylus as its primary input. Typing with the keyboard is just secondary. OneNote is the opposite. Typing first, handwritten second.
OneNote is more appropriate for making a lab report where everything must be typed while Notability is more appropriate for doing math exercises where everything is handwritten.
