你是否还在用下边默认的分页输出，这种方式已经过时了，虽然简短，但是操作优化以及样式拓展方面都存在一些问题。
<?php $this->pageNav('上一页', '下一页', '5', '……');?>

 <style>
        /* 自定义分页导航的样式 */
      .pagination {
            list-style: none;
            display: flex;
            padding: 0;
            margin: 0;
            justify-content: center;
        }
      .pagination li {
            margin: 0 5px;
