title: How to remove gridlines using openpyxl
body: <p>I'm trying to remove gridlines from excel worksheet which I created using openpyxl. I know that it can be done using xlswriter, looking for a openpyxl solution.   I Don't like mixing the two in my code. See code below is not working.  Any suggestive solutions?</p>
  <pre><code>workbook = load_workbook(OutFile1)
  worksheet = workbook['Sheet']
  worksheet.sheet_view.showGridlines = False
  workbook.save(OutFile1)
  </code></pre>
