title: how to add data-attributes to the rows of a JQuery DataTable
body: <p>I would like to had (multiple) data-attributes to the generated rows of my JQuery DataTable so that I can store data in it.</p>
  
  <p>What I want to achieve is to make DataTables generate something like this:</p>
  
  <pre><code>&lt;tr data-foo="bar"&gt;
    &lt;td&gt;&lt;/td&gt;
  &lt;/tr&gt;
  </code></pre>
  
  <p>Is it possible? How to do it? Thanks.</p>
