Use a default sort at load with checkbox

Hi,

I try to make a default sort with checkbox, but i don't success to do it.

In my config i use this : cheked true, but it's not ok.

.columnFilter({
aoColumns:[
{ type: "checkbox", values: [{label:"Non confirmé",value:"0",checked:"true"}, {label:"Confirmé", value:"1", checked:"true"}, {label:"Annulé", value:"2"}, {label:"Archivé", value:"3"}], width:250, height:200},

]
});

Have you an idea ?

Best Regards
