title: jQuery: Find every hidden row
body: <p>This works but it also hides the top border for every cell inside every 2nd row. I only want it to hide the top border IF the first row of each table is hidden. Otherwise it shouldn't hide anything.</p>
  
  <p>I have 4 tables on this page.</p>
  
  <pre><code>var validate = $("tr:nth-child(1)");
  
  if (validate.is(":hidden")) {
      $("tr:nth-child(2) td").css("border-top-width", "0px");
  }
  </code></pre>
  
  <p>Here is an example: <a href="http://jsfiddle.net/nBAgv/" rel="nofollow">http://jsfiddle.net/nBAgv/</a></p>
