jQuery Grid Plugin - jqGrid

Hi,

Can you please help me on how can I show/concatenate two strings in one cell? For example, in my name column, I want to display the firstName and lastName of the person. The data will be coming from a JSON.

JSON:

 {"teamlist":[{"firstName":"Rotchine","lastName":"Canet","resourceID":730,"teamID":897,"teamName":"team 2","usLead":"lead2","usMembers":"member2"}]

Here is part of my code:

  colModel : [{
        name : 'firstName', 
        index : 'firstName',
        width : 55,
        editable:true,
        edittype:'select',
        editoptions: {
         value:codata
         }
       }],   
       

I've tried 'firstName' + 'lastName', but this doesn't work. Is it possible to concatenate two strings in the colModel name property?

Kind regards,

Paolo
