title: Delete multiple columns using column numbers
body: <p>Just wanted to share as I had huge amount of trouble looking for ways to do this online and have finally gotten it through series of trial and error.</p>
  
  <p>Sheet1.Range(Cells(1, 11), Cells(1, 100)).EntireColumn.Delete</p>
  
  <p>This deletes columns 11 to 100.</p>
