How to have elements within a grid on the same line?

Hey guys,

I'm using generatepress premium and generateblocks (apologies if this should have been in the generateblock section)

I'm wondering how can I have all the elements within each rows in a grid (3 columns 5 rows) aligned on the same line so to speak?

You will find in the private info my URL: you'll see the elements in the table aren't aligned, buttons, images, descriptions... they are at a different height from one columns to another.

Thanks a lot for your help,
Marc
