sortable.js

//This code makes the th tag clickable and looks at the data-link tag we set for the url
$(document).ready(function(){
	
	$('.multiSort').click(function(){
		window.location.href = $(this).data('link');
	});
	
});

view.html.erb

<!-- This is how we would use our sortable helper method in our view -->
<table class="zebra-striped">
  <thead>
    <%= sortable "name", "Company" %>
  </thead>
  <tbody>
  <% for company in @companies %>
  <tr>
    <td>
     <%= company.name %>
    </td>
  </tr>
