Is there some way to use already created database table in voyager?

I am using voyager to create admin panel for my app. Link for voyager is https://github.com/the-control-group/voyager. I need to use already created database tables which I created in phpmyadmin but can not find way to do so. Voyager gives some already built tables like categories, menus, pages etc. and also let us create new tables but how can I use my own created tables which I created in phpmyadmin?
