Click on the Project Sponsor ID column that you added and switch to text mode. In order to see the Project Sponsor Name instead, edit the text, replacing anywhere it says "sponsorID" with "sponsor:name" and then save. This column should now populate with the Sponsor's name. Then for "displayname=", you can add in whatever you want to call the column.
