body: <p>Is there a way to apply cell format in <code>xlswriter</code> without setting a value? And in terms of <code>worksheet.write</code> use of A1 notation, can it be done to a range?</p>
  
  <p>Like:</p>
  
  <pre><code>format = workbook.add_format()
  format.set_border(1)
  format.set_bold()
  worksheet.write(row=0, col=0, format=format)
  worksheet.write('A1:C3', format=format)
  </code></pre>
