Creating a Table with WP_List_Table

I’m trying to create a plugin that makes managing shortcodes much like managing posts, except (hopefully) much more intuitive. I have almost everything setup: admin page, general hooks (activation…), and a few other things. The issue I’m having, is that I can’t figure out how to display the entries from the database as a HTML table like with plugins. I’ve tried several guides, but can’t figure it out.

I also need to design the page for editing or creating new shortcodes, but this, obviously, has to come first.
