easyui treegrid 添加复选框

[
{title:'Task Name',field:'name',formatter:function(value,rowData,rowIndex){
return " " + rowData.name;
},width:180},
{field:'size',title:'Persons',width:60,align:'right'},
{field:'date',title:'Begin Date',width:80}
]
});
$("#consle").bind("click",consleclick)
});

function set_power_status(){
var idList = "";
$("input:checked").each(function(){
var id = $(this).attr("id");
if(id.indexOf("ceshi_")>-1)
idList += id.replace("ceshi_",'')+',';
})
alert(idList);
}

function consleclick(){
var node = $('#test').treegrid('expandAll',2);
}


一般会有个checkbox:true的列,删掉他就OK

如果是HTML结构就是<th data-options="field:'ck',checkbox:true"></th>
js结构就是:{field:'ck',title:'选择',checkbox:true},
