**第一步：首先是分页类 把该类放到extend\\page目录下**

<?php
    namespace page;
    
    use think\Paginator;
    
    class Page extends Paginator
    {
    
        //首页
        protected function home() {
            if ($this->currentPage() > 1) {
                return "<a href='" . $this->url(1) . "' title='首页'>首页</a>";
            } else {
                return "<p>首页</p>";
            }
        }
    
        //上一页
        protected function prev() {
            if ($this->currentPage() > 1) {
                return "<a href='" . $this->url($this->currentPage - 1) . "' title='上一页'>上一页</a>";

            }
        }

                .dates li {font-size: 14px;margin:20px 0}
                .dates li span{float:right}
            </style>';
        }
    }

第二步：修改配置文件

`//分页配置`

`'paginate' => [`

`'type' => 'page\Page',//分页类`

`'var_page' => 'page',`

`'list_rows' => 15,`

`],`
