title: SheetJS xlsx-cell styling
body: <p>I am referring this example to export a worksheet <a href="https://github.com/SheetJS/js-xlsx/issues/817" rel="noreferrer">https://github.com/SheetJS/js-xlsx/issues/817</a>. How to do cell 
  styling like background coloring,font size and increasing the width of the 
  cells to make the data fit exactly.I have gone through the documentation but couldn't find any proper examples to use fill etc.Is there a way to do the formatting?</p>
  
  <pre><code>Below is the code snippet:
      /* make the worksheet */
  var ws = XLSX.utils.json_to_sheet(data);
  
  /* add to workbook */
  var wb = XLSX.utils.book_new();
  XLSX.utils.book_append_sheet(wb, ws, "People");
  
  /* write workbook (use type 'binary') */
  var wbout = XLSX.write(wb, {bookType:'xlsx', type:'binary'});
  
  /* generate a download */
  function s2ab(s) {
      var buf = new ArrayBuffer(s.length);
      var view = new Uint8Array(buf);
      for (var i=0; i!=s.length; ++i) view[i] = s.charCodeAt(i) &amp; 0xFF;
      return buf;
  }
  saveAs(new Blob([s2ab(wbout)],{type:"application/octet- 
  stream"}),"sheetjs.xlsx");
  </code></pre>
