First try this class on your template grid:
If that doesn’t do quite what you need, you can customize your UI with CSS. I’d recommend setting up Calypso as described here to easily edit the Mendix Atlas styling files: https://docs.mendix.com/howto/front-end/calypso
Would I put that class under the “Common” section of the Properties?
I should have mentioned I have an embedded table widget within my template grid … I tried applying the same classes to the table widget, but the output still appears like this … Sounds like I might have to use Calypso?
