title: Find and replace text in first column of tables
body: <p>I have a document with multiple tables and I need to look <strong>only</strong> in every cell of first column and do the next replacement:</p>
  
  <ul>
  <li><em>find:</em> ([0-9]{1;2}).^s</li>
  <li><em>replace:</em> \1.^p</li>
  </ul>
  
  <p>Is it possible to choose in which column to look, in order to use it for other documents, replacements?</p>
