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

不用vue框架写一个table
<!DOCTYPE html>
<html lang="en">
<head><meta charset="UTF-8"><meta name="viewport" content="width=device-width, initial-scale=1.0"><title>测试用例管理平台</title><script src="https://unpkg.com/vue@3/dist/vue.global.js"></script>
</head><body><div calss="table" style="display: inline-block"><h2>测试用例</h2><button class="add-case-button" @click="isEdit=true">新增用例</button><table border="2"><col style="width: 100px; overflow: hidden; text-overflow: ellipsis" /><col style="width: 100px" /><col style="width: 100px" /><col style="width: 100px" /><col style="width: 100px" /><tr><th>用例名</th><th>步骤名</th><th>关键字</th><th>参数1</th><th>参数2</th><th>操作</th></tr><tr><td>参数正确登录成功</td><td>输入正确的参数登录成功</td><td>用户名 密码</td><td>用户名</td><td>密码</td><td><button>删除</button></td></tr><tr><td>参数错误登录失败</td><td>输入错误的参数登录失败</td><td>用户名 密码</td><td>用户名</td><td>密码</td><td><button>删除</button></td></tr><tr><td>参数为空登录失败</td><td>输入的参数为空登录失败</td><td>用户名 密码</td><td>用户名</td><td>密码</td><td><button>删除</button></td></tr></col></table></div>
</body></html>
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！

</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！
