title: How to set column width of XLSX worksheet in angular4
body: <p>I am Converting HTML to  XLSX sheet in angular using SheetJS. But the width of each column is 256 only, I want to increase it </p>
  
  <p>I have tried using ws[!cols] of ColInfo but not able to correctly implement it or set it 'wch' &amp; 'width'</p>
  
  <pre><code>let worksheet: XLSX.WorkSheet = XLSX.utils.json_to_sheet(this.exportNoteData);
  
  const workbook: XLSX.WorkBook = { Sheets: { 'data': worksheet }, SheetNames: ['data'] };
  XLSX.writeFile(workbook, 'NoteExport.xls', { bookType: 'xls', type: 'buffer' });
  </code></pre>
  
  <p>I want to provide custom width for each column in generated excel, currently, I have 4 fixed columns</p>
