Ok the link mentions that the formatting works at the presentation level & not at the business logic or underlying calculation stage. So once you are done with the number calculation of Bytes, you could format or in other display raw Bytes with suffix/prefix plus comma or any other delimiter separated strcutured formatted number. The code example should work for one column at a time, repeated for all columns you want to be reformatted, by way of a script.
