body: <p>I have a table with values similar like:</p>

  <pre><code>Argentina
  ----------------
  Fede      22  M

  Colombia
  ----------------
  Pablo     32  M
  ----------------
  USA
  ----------------
  Paul      24  M
  ----------------
  Sarah     31  F
  </code></pre>
  
  <p>I don´t know how I can obtain a similar result like that.</p>
