Interested in ways you have structured your KB with longer documents like procedures/job aids with step by step processes? We have the record types with different fields on the page layouts but this is more specific to the format once within the rich text fields.
Right now we use tables in another system, but it is a big undertaking to make sure they are correct prior to publishing. Doesn't look like you can pre-populate a "template" within the rich text fields. So, have any of you used a more simple format that is easy for your users to follow step-by-step without tables?
Just a side note if you need to take accessibility into account for your audience. Tables can be awful for screen readers. If you use them, you'll want to be sure to incorporate summary/caption/headers and make sure they're as flat and simple as possible.
