The Randomizer comes with about a bazillion tables already established.
The download links are for the current version (as of September 5th, 2016), but news about updates, along with a link to the download site, can be located in this Reddit thread.
From that thread: "The Randomizer is an always free and open source Windows application designed with role-playing games and story tellers in mind. It is a customizable random thing generator able to generate nearly limitless things including and certainly not limited to names, plot hooks, and maps."
The download is small and installation was extremely quick.
