Hello,

You can set Revise the column on mobile https://prnt.sc/vkzuuv as the result the column will go one under another in the right order.

If you want to add a gap on mobile, add a column in the top and hide it on desktop, table and other devices https://wpbakery.com/video-academy/control-elements-different-devices-responsive-column-controls/

If you mean something different, please clarify.

Best Regards
