title: How to select td when you know th text with jquery
body: <p>I have a table containing rows with exactly one th and one td like this:</p>
  
  <pre><code>&lt;tr&gt;
    &lt;th&gt;Phone Number&lt;/th&gt;
    &lt;td&gt;555-555-1212&lt;/td&gt;
  &lt;/tr&gt;
  </code></pre>
  
  <p>I need to select the td cell (and replace the html) by using the th text "Phone Number".  I can get the th cell with</p>
  
  <pre><code>$('th:contains("Phone Number")')
  </code></pre>
  
  <p>but I can't figure out how to select the corresponding td cell.</p>
