When getting to the part where you choose a template for your table, you might encounter a blank screen with no table settings visible.
Occasionally, users have certain settings that have turned off the Gutenberg builder or forced the legacy classic WordPress editor to turn on (switching off the Gutenberg builder). You might have a plugin or theme that defaults to the legacy WordPress editor or a setting to turn off the Gutenberg builder. Different plugins/themes use different terms for turning off Gutenberg. Without knowing all the plugins and theme you use, it is hard to say specifically which software might cause this.
If you are not sure which plugin or theme it is, you can try turning them off one by one until the pricing table editor appears like the screenshot below.
Just to clarify, Gutenberg is only needed to build the table and not needed for the whole site.
