title: Laravel Excel vertical align center
body: <p>How can I verticaly align center cells with laravel Excel ?</p>
  
  <p>My code :</p>
  
  <pre><code>$sheet-&gt;cells('A1:'.$column_end.$i, function ($cells) {
                  $cells-&gt;setBackground('#d8d8d8');
                  $cells-&gt;setFontWeight('bold');
                  $cells-&gt;setValignment('middle');
              });
  </code></pre>
  
  <p>But it doesn't work, most of my cells are vertically align bottom.</p>
  
  <p>Maybe it's not middle !</p>
  
  <p>I tried 'center' but it didn't work neither. When I tried 'top' or 'bottom' it worked. </p>
  
  <p>So why 'middle' or 'center' didn't ?</p>
  
  <p>Thank for your help. </p>
