title: ClosedXML enable Autofilter in protected sheet
body: <p>I am adding an Autofilter to my worksheets and protect my worksheet:</p>
  
  <pre><code>oSheet.Range(StartRange, EndRange).SetAutoFilter();
  oSheet.Protect("xxxx");
  </code></pre>
  
  <p>Obviously this has the effect of disabling the Autofilter, which i need enabled. I have tired to add:</p>
  
  <pre><code>oSheet.AutoFilter.Enabled =true;
  </code></pre>
  
  <p>Both before and after the protect statement to no effect. I have also tried to add the filter after the sheet protection. Also no effect. Am I missing something ?</p>
