Refreshing an NSTableView with an NSMutableArray dataSource

I know this is a horrible newbie question but I am hoping that someone 
can simply confirm that I'm not missing something. Am I correct in 
assuming that the only way to reflect changes made to an 
NSMutableArray in an NSTableView which is using the array as a 
dataSource is by using reloadData?

Please note that this is all being done via delegates and not by 
Bindings and I am doing the challenge at the end of chapter 6 of 
Aaron's book (3rd edition).

Many thanks.

Simon
