title: How to get cell by name with exceljs?
body: <p>For now, I have to hardcode like this</p>
  
  <pre><code>var cell = worksheet.getCell('A1');
  </code></pre>
  
  <p>But I want to define my cell by name like <code>data</code> and access the cell by: </p>
  
  <pre><code>var cell = worksheet.getCell('data');
  </code></pre>

  <p></p>
  
  <p><strong>How can I do that with exceljs ?</strong>
  Thank you very much!</p>
  
  <p>Note: The only solution seems to solve my problem is to add column/row headers and define key, but I don't want to do that in my code:</p>
  
  <pre><code>worksheet.columns = [
    { header: 'Id', key: 'id', width: 10 }
  ];
  </code></pre>
