Essentially the genre column is standard in calibre, it is just called the tags column. Tags
are the generic industry metadata standard for applying labels to items in the internet and so has been the default value for what you call the genre column.
Amazon.com was one of the first sites calibre used where you could grab the "tags folks assigned to books" from the bottom of any book page. Since then sites like the Sony book store and Barnes and Noble book stores have called them Subjects. While Goodreads and Fantastic Fiction now label their books by Genre. Currently it seems that Tags, Subjects, or Genre in the land of eBook metadata are roughly synonymous.
