title: Insert text into a jQuery object of table cells at certain index
body: <p>Is the following possible to accomplish?</p>
  
  <p>Given a string of table cells:</p>
  
  <pre><code>var str = "&lt;td&gt;&lt;/td&gt;&lt;td&gt;&lt;/td&gt;&lt;td&gt;&lt;/td&gt;";
  </code></pre>
  
  <p>Is that possible to convert this string into a jQuery object like this and add text to any table cell by the index:</p>
  
  <pre><code>var index = 1;
  $(str).eq(index).text("Some text");
  </code></pre>
  
  <p>And after that convert the object back into a string to concatenate with the rest of the table cells in an existing table.</p>
  
  <p>The code above does not seem to work. Is there any way to do this?</p>
  
  <p>Thanks.</p>
