Allow adding table for has_many assocation in 'show' page

[jesseduffield]

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.
