Bring other fields into a child or parent field using lookup field type

Anyone know how to get other fields to come into a record from a child or parent record? I have a lookup function in a table and I am trying to get it to bring additional information from the table with the parent record. If I choose the name of the record, for instance, I want it to bring other fields, such as address or phone number, from that record into the parent record.
