Sometimes, you may want to hide gridlines or column headers in your table to change the way that it's displayed. Or you may want to collapse your table under a heading and don't need its title to show. 

To hide some or all of these displays, hover your cursor over the upper righthand side of your table until the menu appears, then click "Options." Once the sidebar menu opens, select "Table display." From there, you can toggle each of them from on > off.

Here's a gif of what that looks like: 

Note that these changes apply to individual views, so making the change to one view won't change others!
