前言

前面学习了前端HMTL、CSS样式、JavaScript以及Vue框架的简单适用，接下来运用前面的基础继续学习Vue，运用前端模块化编程的思想。

响应式基础 ref reactive

关于ref和reactive，官方解释如下，另外一篇博客写得也很清楚

上面的实现方式用到了很多个th、td标签，维护很麻烦，那有没有更好的解决方法？

如何用vue框架实现？

用v-for，遍历数组中的元素，进行列表的渲染。

关键两行代码：

取列表的表头，表头名称前加上编号，编号从1开始

<th v-for="(Name,key,index) in tableName " :key="key">{{index+1}}{{Name}}</th>

取列表里具体的内容

<tr v-for="testCase in testCases" >

如果要修改表头、列表里内容，不需要在标签里一个一个改，只需要去维护tableName、testCases里的值即可。是不是很省劲！

        };
        createApp(MRJJ).mount('#test');
    </script>
</body>

</html>

可以看到td标签里的内容自动取出来了。

踩坑记录：

createApp(MRJJ).mount('#test');

id为test这个div标签里的内容，才能引用MRJJ里面的方法。

结合前面的内容，最终写出来的页面！
