title: Adding print titles to a worksheet using openpyxl
body: <p>I'm unable to add print titles to my Excel worksheet using openpyxl. The named range is created properly but it doesn't properly become the named range for the print titles. The problem seems to be that the scope of the print titles named range is incorrect (at least, if I am understanding it correctly). Instead of the scope being the worksheet name as it is if I create print titles manually in Excel, the scope is always 'Workbook'. Here's a relevant snippet of the code I'm using:</p>
  
  <pre><code>wb = Workbook()
  ws = wb.active
  ws.add_print_title(1, rows_or_cols='rows')
  </code></pre>
  
  <p>As far as I can tell <code>add_print_title</code> only needs the number of rows or columns to add to the named range and whether rows and columns are being added. And like I said, this creates a named range properly, it just doesn't make that named range into the print titles. Maybe I'm missing something silly, but I've exhausted all Google searches and my little bit of knowledge. </p>
