Allow adding table for has_many assocation in 'show' page

**Is your feature request related to a problem? Please describe.**
Right now if you have a has_many association in a show page, it just shows as a list of links to the associated records. This is not very user-friendly if you're dealing with a lot of records.

**Describe proposed solution(s)**
 I'd like to have an option to show a table inline with its own pagination/filtering.
