tablifer provides an ActionView helper method that will generate an html table displaying the attributes of an ActiveRecord (or ApplicationRecord) object or the key-value pairs of a Hash.

Ruby version >= 2.0. This gem was written with Rails in mind, but the only real requirements are ActionView and Railties. It's been tested with ActiveRecord versions ~> 4.1 as well as ApplicationRecord for Rails 5.

Add to your Gemfile:

gem 'tablifier', '~> 1.1'

Next, bundle install. You can style generated tables yourself or use the included stylesheet (demonstrated in the above screenshot) by adding to app/assets/stylesheets/application.css:

/*
 *= require tablifier
 */

In an ERB view, call the tablify method and pass the object you'd like tablified:

<h3>A tablified hash:</h3>
<%= tablify {first_key: 'first_value', second_key: 'second_value'} %>

<h3>A tablified ActiveRecord object:</h3>
<%= tablify MyModel.first %>
