title: How to hide certain columns for a user?
body: <p>On a shared Google spreadsheet:</p>
  
  <p>I don't want a <strong>specific</strong> user in my domain to view columns with sensitive data, but this person should still be able to edit the rest of the spreadsheet. </p>
  
  <p>I tried creating a 'master' spreadsheet and using importrange to bring the data into a 'shared' sheet, but once I edit any cell in the shared spreadsheet, importrange no longer works as the sheet is emptied out.</p>
  
  <p>Is there a quick way to do this, maybe using scripting?</p>
