title: How to lock and protect columns but allow rows to be edited
body: <p>I've Put in a code into a sheet so when the user double clicks on the cell, a new row is added below and the formulas are dragged down. </p>
  
  <p>I'm wanting to disable the option to delete or insert any columns but allow rows to be inserted or deleted. </p>
  
  <p>I've tried to lock and protect columns being edited, however it's stopping the rows from being edited.</p>
  
  <p>Is this even possible? </p>
