Hello,
I was following along with the Creating a Simple App course, and noticed that when the instructor added a table, it did not appear to have gridlines. I searched for a menu option to turn gridlines off, and could not find one.
The suggestions I've found so far all pertain to QlikView and mention a Settings-->User Preferences->Design section. Is that something we have in Qlik Sense?
This seems like a simple functionality, so I don't know if I'm over-complicating this and just missing it somewhere.
