title: phpexcel line break automatically
body: <p>I refered this question 
  <a href="https://stackoverflow.com/questions/13071752/how-to-set-auto-line-break-phpexcel">How to set auto-line break PhpExcel?</a></p>
  
  <p>But I am little unclear. So here's the question.</p>
  
  <p>I am getting a paragraph from the <code>$content</code></p>
  
  <p>If i directly do the <code>$objPHPExcel-&gt;getActiveSheet()-&gt;setCellValue('A9', $content);</code> i am not getting line breaks, </p>
  
  <p>I just want to make it like exact way did in the 05featureddemo.inc.php</p>
  
  <p>It says to do <code>$objPHPExcel-&gt;getActiveSheet()-&gt;setCellValue('A3', $sLloremIpsum);</code> But i can't find where the size of the coloumn given, i.e., </p>
  
  <p>I ask because even if i remove the style from the below array</p>
  
  <pre><code>$objPHPExcel-&gt;getActiveSheet()-&gt;getStyle('A3:E3')-&gt;applyFromArray(
          array(
              'font'    =&gt; array(
                  'bold'      =&gt; true
              ),
              'alignment' =&gt; array(
                  'horizontal' =&gt; PHPExcel_Style_Alignment::HORIZONTAL_RIGHT,
              ),
              'borders' =&gt; array(
                  'top'     =&gt; array(
                      'style' =&gt; PHPExcel_Style_Border::BORDER_THIN
                  )
              ),
              'fill' =&gt; array(
                  'type'       =&gt; PHPExcel_Style_Fill::FILL_GRADIENT_LINEAR,
                  'rotation'   =&gt; 90,
                  'startcolor' =&gt; array(
                      'argb' =&gt; 'FFA0A0A0'
                  ),
                  'endcolor'   =&gt; array(
                      'argb' =&gt; 'FFFFFFFF'
                  )
              )
          )
  );
  
  $objPHPExcel-&gt;getActiveSheet()-&gt;getStyle('A3')-&gt;applyFromArray(
          array(
              'alignment' =&gt; array(
                  'horizontal' =&gt; PHPExcel_Style_Alignment::HORIZONTAL_LEFT,
              ),
              'borders' =&gt; array(
                  'left'     =&gt; array(
                      'style' =&gt; PHPExcel_Style_Border::BORDER_THIN
                  )
              )
          )
  );
  </code></pre>
  
  <p>and make it as </p>
  
  <pre><code>$objPHPExcel-&gt;getActiveSheet()-&gt;getStyle('A3:E3')-&gt;applyFromArray(
          array(
  
          )
  );
  
  $objPHPExcel-&gt;getActiveSheet()-&gt;getStyle('A3')-&gt;applyFromArray(
          array(
  
          )
  );
  </code></pre>
  
  <p>It works,</p>
  
  <p>So the question is how can i set the line break for particular coloumn and group of coloumn  for 20px say)</p>
