jquery easyui datagrid columns的title和field怎么在同一行显示

代码是这样的
        $('#querySelectTable').datagrid({
                width : 1001,
                collapsible : true,
                nowrap :true,               
                url : '<%=request.getContextPath()%>/app/website/count/GetArticleSelectCount.action',
                columns : [ [
                {
                    title:'文章搜索功能使用次数',
                    field:'selectCount',
                    width : 998,
                }
             ] ]
            });
