How to refresh table fields?

Hello all, I am somewhat new to developing in Crystal Reports, using Crystal Reports 11, and have a question. What is the easiest way to refresh the fields information about the tables in your report? For example, if a report was made, and then a field was added to a table the report uses, I notice it doesn't appear in the Crystal Reports field explorer.

I've gotten around it earlier by removing and re-adding the table in the database expert, but that loses everything on the report from that table, so I would imagine there is a better method, but have been unable to find it. Anyone know a better way to refresh the table fields in the field explorer?

I'd appreciate any responses, thanks.
