需要提前下载相关依赖哈，nanoid

样式：

     /* 基础表格样式 */table {border-collapse: collapse;/* 关键：合并边框 */width: 100%;font-family: Arial, sans-serif;}/* 设置所有单元格边框 */th,td {border: 2px solid #7adb59;/* 1px实线边框，颜色自定义 */padding: 8px;text-align: left;background-color: #c9edd8;}/* 表头样式 */th {background-color: #c9edd8;border-color: #7adb59;/* 表头边框颜色可不同 */}

小结

实现代码中，我创建了mock data。只有简单的四条而已哈；如果想看更多数据的搜寻，可以自己再多创建几条数据；
使用到hook有 useEffect, useState，useNavigate, useSearchParams；
nanoid() 是可以生成随机唯一的id的
useNavigate 是可以跳转路由的
useSearchParams 是可以获取路由的参数的
