Unsure how to use the reservation form app

I would like to add a seating plan to my reservation form. 

I have seen this app: http://apps.jotform.com/app/reservation_form

I am unsure how to use it though. The guidance is not too clear. 

How do I view entries? How do I add it to my form? 

Thanks you
