I just opened a pull request to add this functionality: https://github.com/gregbell/active_admin/pull/2812

Which lets you use arbitrary data in a table, like this:

table_for foo: 1, bar: 2 do
  column :foo
  column :bar
end

Please give the pull request a try by putting this in your Gemfile:

gem 'activeadmin', github: 'seanlinsley/active_admin',
                   branch: 'feature/1713-support_arbitrary_objects_for_tables'

UPDATE

This has now been merged into master:

gem 'activeadmin', github: 'gregbell/active_admin'
