Add Fields to Customer Search Results

[AndyBDS]

I would like to add an additional field to the search results under the customer tab. Currently it shows Username, Name, Email, CustomerID, Last Login, and Valid. I have created the company_id field for the customers and would like that to show in the results as well.

Currently using 3.0.4 CentOS 5.5

Which config file do I need to edit to so this? Thanks in advance!
