调整phpexcel中的行高

Question

我刚刚试图让phpexcel（PHPExcel_Writer_Excel2007）根据内容自动调整行高，但内容中包含换行符。目前，只有最后一行可见。我已经尝试将行高设置为-1，对于有问题的行和整列，即

<form class="form">
  <p>Potencia a Instalar (Watts)
    <br />
    <span class="form"><input type="text" name="watts_to_install" value="" size="40" id="watts_to_install" required />
    </span>
  </p>
  <p>Panel a ser utilizado<br />
    <span class="form">
      <select name="panel" class="form" id="panel">
        <option id="Hanwha">Hanwha 250W</option>
        <option id="Sharp">Sharp 250W</option> 
      </select>
    </span>
  </p>
  <button onclick="Process1()">Nivel 1</button>
  <span class="form">
    <p>Potencia Maxima de Panel</p>
    <input type="text" id="max_power" value="">
    <br />
    <p>Cantidad a Instalar</p>
    <input type="text" id="quantity" value="">
  </span>
</form> 

<script type="text/javascript">
function Process1()
{
    var power = document.getElementById('watts_to_install').value;
    var panel = document.getElementById('panel').value;
    switch(panel)
    {
       case 'Hanwha':
          var power_panel = 250;
          var panel_quantity = power/power_panel;

          document.getElementById('max_power').value = power_panel;
          document.getElementById('quantity').value= panel_quantity;
          break;
       case 'Sharp':
          break;
   }
}
</script>

和

$objPHPExcel->getActiveSheet()->getRowDimension(65)->setRowHeight(-1);

但没有区别。帮助赞赏。干杯
