title: PHPExcel: Setting font size?
body: <p>I have been looking to change the font size of some Excel cells using a PHP library called PHPExcel. </p>
  
  <p>This is what I tried:</p>
  
  <pre><code>$objPHPExcel-&gt;getActiveSheet()-&gt;getStyle("F1:G1")-&gt;getFont()-&gt;setFontSize(16);
  </code></pre>
  
  <p>The method above does not work. I was wondering if anyone knows how to do this?</p>
  
  <p>Many thanks in advance.</p>
