title: Changing table row height
body: <p>I am trying to change the row height of a table belonging to a particular class to 0. </p>
  
  <p>Currently I am doing  this:</p>
  
  <pre><code>$("#table_rolecart tbody").append('&lt;tr class='hide'&gt;&lt;td&gt;Start Date: &lt;input type="text" value="" id="ar_startdate"&gt;&lt;/td&gt;&lt;td&gt;End Date: &lt;input type="text" value="" id="ar_enddate"&gt;&lt;/td&gt;&lt;/tr&gt;');
  $('.hide').height = "0"
  </code></pre>
  
  <p>It's still not zero, how do I set the height to 0 or set display style to none for those <code>&lt;tr&gt;</code>s?</p>
