thinkadmin中联表查询的使用

$this->_query($this->table)
            ->alias('a')
            ->field('a.id,a.audit_name,b.supplier_name,a.contract,a.audit_status,a.is_del,a.create_time_auto,a.supplier_id')
            ->join('rht_supplier_info b','a.supplier_id=b.id')
            ->like('a.id#id,a.audit_name#audit_name')
            ->order('a.create_time desc')
            ->page();
