Anybody know how to hide the first column on the mvc grid with Jquery or javascript? It is a checkbox. I've tried all of these below. No luck:

                var grid = $("#ClaimDetailsGrid").data("t-grid");
                var columnA = grid.columns[0];  //works 
                //columnA.readonly = true;         //no worko
                //columnA.hidden = true; //no worko 
                columnA.attr('hidden', 'true'); //no worko 
columnA.attr('readonly', 'readonly'); //no worko 

At this point I'd settle for disabling it, hiding it anything. 

Thanks
