Easyui datagrid 实现外键字段转义

推荐人，关联的是同一张表的ID，怎么让1显示张，

  page = page == null ? 1 : page;
            rows = rows == null ? 1 : rows;
            List<TBL_M_SECURITY_STAFF> list = db.TBL_M_SECURITY_STAFF.OrderBy(a => a.Security_Staff_ID).Skip((Convert.ToInt32(page) - 1) * Convert.ToInt32(rows)).Take(Convert.ToInt32(rows)).ToList();
                        var json = new
            {
                total = db.TBL_M_SECURITY_STAFF.Count(),
                rows = list.Select(a => a)
            };
                         return Json(json, JsonRequestBehavior.AllowGet);

sql left join下自身取出推荐人名字

 select t1.xx,t1.xxx,t1.xxxxx....,t2.推荐人名字
from yourtable t1
left join yourtable t2 on t2.推荐人id=t1.记录唯一id
