[响应式基础 ref reactive](#响应式基础 ref reactive)
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
html
<!DOCTYPE html>

<div calss="table" style="

<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" />
<tr>
<th>用例名</th>
<th>步骤名</th>

<tr>

<td>输入正确的参数登录成功</td>

<tr>

<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>

</col>
</table>

</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！

const { createApp, computed, ref, reactive } = Vue;
const = MRJJ{
setup() {
let tableName = reactive({
"caseName": "用例名",
"stepName": "步骤名",
"keywords": "关键字",
"param1": "参数一",
"param2": "参数二",
"opration": "操作",
})
let testCases = ref([
{
"id": 1,
"caseName": "参数正确登录成功",
"stepName": "登录成功",
"keywords": "用户名",
"param1": "用户名",
"param2": "密码",
"opration": "删除"

{
"id": 2,
"caseName": "参数错误登录失败",
"stepName": "登录失败",
"keywords": "用户名",

"param2": "密码",
"opration": "删除"

"opration": "删除"
},
])
return { tableName, testCases }
}
};
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！
