adding a Row-Total Column?

Hi all,

Is there a way to add a final column to a table so that it shows the sum of values foreach row? The "footer" functions work beautifully, and I'm thinking that people like to add their rows as well as their columns. Is there a good way to do this?

This seems like an obvious sort of application, but I don't see it addressed anywhere.

Any ideas?

Thanks,
Ken
