title: add margin-top and bottom on a div in a table with mpdf
body: <p>I am facing a problem when i try to add the <em>margin-top</em> or <em>margin-bottom</em> on div elements inside a table for generating pdf with <strong>mpdf</strong>.</p>
  
  <p>I have something like this:</p>
  
  <pre><code>&lt;table&gt;
  &lt;tr&gt;
      &lt;td&gt;
          &lt;div style="margin-top: 20px;"&gt;Element1&lt;/div&gt;
          &lt;div style="margin-top: 20px;"&gt;Element2&lt;/div&gt;
          ...
      &lt;/td&gt;
  
      &lt;td&gt;
          &lt;div style="margin-top: 20px;"&gt;Element4&lt;/div&gt;
          &lt;div style="margin-top: 20px;"&gt;Element5&lt;/div&gt;
          ...
      &lt;/td&gt;
  &lt;/tr&gt;
  &lt;/table&gt;
  </code></pre>
  
  <p><strong>The margin styles are not converted.</strong></p>
  
  <p>I think it could be because there are too many nested elements and mpdf doesnt support them in some cases. Have someone already achieved such a problem?</p>
