title: Not able to set border to a column - phpexcel
body: <p>I am using <strong>PhpExcel</strong> for my application.
  When I use this below code to set border for an individual cell, it works fine. But when I use it for all cells in a column ('A') it throws the below error:</p>
  
  <blockquote>
    <p>Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 24 bytes) in C:\xampp\htdocs\rat\xls-class\PHPExcel\Worksheet.php on line 1219</p>
  </blockquote>
  
  <p>Defining border style:</p>
  
  <pre><code>$border_style= array('borders' =&gt; array('right' =&gt; array('style' =&gt; PHPExcel_Style_Border::BORDER_THIN)));
  </code></pre>
  
  <p>Applying to all cells in column 'A':</p>
  
  <pre><code>$sheet-&gt;getStyle("A")-&gt;applyFromArray($border_style);
  </code></pre>
