tp5的分页循环

$page = Db::table('building_details_set')->paginate('15')->each(function($item,$key){
        if(is_array($item) && !empty($item)){
            $wctypeid = $item["clumr_id"]; //获取数据集中的id
            $list = db('building_column')->where('id',$wctypeid)->find();
            $item['clumr_id'] = $list['name'];
            return $item;
        }
    });
