title: PHPExcel setWrapText(true) not working
body: <p>I have a serious problem with text wrapping via PHPExcel. I have a column, which contains texts in new lines. It does the linebreaks in LibreOffice. In MS Office it is displayed in a single line. In both viewers, it only does the wrap, when I double click into a cell and then click out the cell. I have the following code:</p>
  
  <pre><code>foreach($view-&gt;results as $row){
      //...
      foreach($unserialized as $task){
        $value = $field_info['settings']['allowed_values'][$doc['document']];
        $current_tasks .= $value . "\n";          
      }
    $active_sheet-&gt;setCellValue($letter.$i, $current_tasks); 
    //...
    //end of main foreach loop
    $active_sheet-&gt;getStyle('L' . $i)-&gt;getAlignment()-&gt;setWrapText(true);
    $i++;
  }
  //tried this too outside the foreach:
  $active_sheet-&gt;getStyle('L2:L' . $i)-&gt;getAlignment()-&gt;setWrapText(true);
  </code></pre>
  
  <p>They don't seem to be working. Am I doing something wrong? I googled it up and neither of the solutions worked for me. </p>
