Display a custom column to Service Desk view

Hi everybody,

I need your help to know how to display a custom column (eg: company_cust_number_contrat) presents in the company table in the Service Desk dashbord and/or Custom View.
How to do that?

For information in Help Desk Settings > Customize > Fields Customization, in the Custom Column tab exist.
About the custom column:
Field Caption = Numero de contrat
Entity Type = Company
Field Type = Integer
DB Field Name = company_cust_number_contrat

Many thanks in advance for your replies.
