先看效果

第一步：首先是分页类 把该类放到extend\page目录下

// +----------------------------------------------------------------------

use think\Paginator;

class Page extends Paginator
{

    //首页
    protected function home() {
        if ($this->currentPage() > 1) {
            return "url(1) . "' title='首页'>首页";
        } else {
            return "
首页
";
        }
    }

    //上一页
    protected function prev() {
        if ($this->currentPage() > 1) {
            return "url($this->currentPage - 1) . "' title='上一页'>上一页";
        } else {
            return "
上一页
";
        }
    }

    //下一页
    protected function next() {
        if ($this->hasMore) {
            return "url($this->currentPage + 1) . "' title='下一页'>下一页";
        } else {
            return"
下一页
";
        }
    }

    //尾页
    protected function last() {
        if ($this->hasMore) {
            return "url($this->lastPage) . "' title='尾页'>尾页";
        } else {
            return "
尾页
";
        }
    }

    //统计信息
    protected function info(){
        return "
共" . $this->lastPage .
            "页" . $this->total . "条数据
";
    }

    /**
     * 页码按钮
     * @return string
     */
    protected function getLinks()
    {

        $block = [
            'first'  => null,
            'slider' => null,
            'last'   => null
        ];

        $side   = 3;
        $window = $side * 2;

        if ($this->lastPage < $window + 6) {
            $block['first'] = $this->getUrlRange(1, $this->lastPage);
        } elseif ($this->currentPage <= $window) {
            $block['first'] = $this->getUrlRange(1, $window + 2);
            $block['last']  = $this->getUrlRange($this->lastPage - 1, $this->lastPage);

            $block['last']  = $this->getUrlRange($this->lastPage - ($window + 2), $this->lastPage);
        } else {
            $block['first']  = $this->getUrlRange(1, 2);
            $block['slider'] = $this->getUrlRange($this->currentPage - $side, $this->currentPage + $side);
            $block['last']   = $this->getUrlRange($this->lastPage - 1, $this->lastPage);
        }

        $html = '';

        if (is_array($block['first'])) {
            $html .= $this->getUrlLinks($block['first']);
        }

        if (is_array($block['slider'])) {
            $html .= $this->getDots();
            $html .= $this->getUrlLinks($block['slider']);
        }

        if (is_array($block['last'])) {
            $html .= $this->getDots();
            $html .= $this->getUrlLinks($block['last']);
        }

        return $html;
    }

    /**
     * 渲染分页html
     * @return mixed
     */
    public function render()
    {
        if ($this->hasPages()) {
            if ($this->simple) {
                return sprintf(
                    '%s

                    $this->css(),
                    $this->prev(),

                );
            }
        }
    }

    /**

    protected function getAvailablePageWrapper($url, $page)
    {
        return '' . $page . '';
    }

    /**

     *
     * @param  string $text
     * @return string
     */
    protected function getDisabledTextWrapper($text)
    {
        return '

    }

    }

     *

     */
    protected function getUrlLinks(array $urls)
    {
        $html = '';

        foreach ($urls as $page => $url) {
            $html .= $this->getPageLinkWrapper($url, $page);
        }

        return $html;
    }

    /**
     * 生成普通页码按钮
     *
     * @param  string $url

     * @return string
     */
    protected function getPageLinkWrapper($url, $page)
    {
        if ($page == $this->currentPage()) {

        }

        return $this->getAvailablePageWrapper($url, $page);
    }

    /**
     * 分页样式
     */
    protected function css(){
        return '  ';
    }
}

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,
    ],
