title: jquery using .filter() to check two td:nth-child(x) conditions
body: <p>I need to filter based on 2 conditions in jquery on a table and certain <code>td</code> contents. I can filter one, I am not sure how to filter based on two though. I need to filter both the 3rd <code>AND</code> the 8th <code>td</code> in one shot.</p>
  
  <pre><code>$('.searchable tr').filter(':has(td:nth-child(3):contains("Open"))').show();
  </code></pre>
  
  <p>This one filters only the third.</p>
  
  <p>I know how to filter just based on class names like</p>
  
  <pre><code>$(selector).filter('.one, .two');
  </code></pre>
  
  <p>using OR and</p>
  
  <pre><code>$(selector).filter('.one.two');
  </code></pre>
  
  <p>using AND</p>
  
  <p>But I am not sure how to combine mine since it is contained in <code>''</code></p>
