body: <p>It's possible create this table with rowspan ??</p>
  
  <pre><code>|---------|---------|  
  | 1       |4        |
  |---------|         |
  | 2       |---------| 
  |---------|5        |
  | 3       |         |
  |---------|---------|
  </code></pre>
  
  <p>Every row inside the second column have 1.5 ?</p>
  
  <p>I think that its possible play with the attribute 'height' or maybe create another table inside the second column...</p>
  
  <p>But is it possibble only with rowspan or colspan?</p>
