how can I put colums in a specific group?

I want to put column on a specific group so it will look like in a details view..

However how can I put customized columns like a column for item name, and another column for other details, on a specific groups...

for example If I have a group of Software vendors, the items "Microsoft", "Infragistics", "Suns", should be viewed in detail look style.. it should look like the example below, only on graphics...

(Group Name Header) "Software Vendors"

          CompanyName                                 Status                    Location
