The price list below keeps its spacebar alignment because Real Editor Space converts the extra spaces to non-breaking spaces. Without the plugin, Gutenberg collapses them and the columns fall apart.

Basic Care Plan           $49/mo
Standard Care Plan     $99/mo
Priority Care Plan         $199/mo

For the live demo, the better moment is typing it fresh: open a draft, hit the spacebar a few times between plan and price, publish, and show the front end keeping every space.
