如何获取单个vue文件所生成的页面？

我们的开发的过程中会接触不少开源项目，他们都各有所长，偶尔看到有些好的场景，自己想拿来使用，但又不想使用重构整个项目，仅仅只想使用某个组件（vue）那么该如何使用呢？
比如我需要下图中这个页面的布局和实现：
image.png
于是我找到它对应的 vue 文件
其源代码如下所示：
<template>
<el-dialog width="900px" :title="data?'修改表 '+data.name:'创建表'" :visible.sync="is_visible" @close="on_close">
<el-form size="small" label-width="60px" style="margin-right: 30px">
<el-row>
<el-col :span="12">
<el-form-item label="表名:" :error="String(errors.name?errors.name:'')">

</el-form-item>
</el-col>
<el-col :span="12">
<el-form-item label="别名:" :error="String(errors.alias?errors.alias:'')">

</el-row>

它依赖项目的 api 文件夹，还依赖 element-ui。
我不想重构现有的前段设计，只想使用这个小页面。
我查了查官方的解决方案：使用 vue-cli 脚手架提供的 vue serve 功能可以快速原型开发：
可以使用 vue serve 和 vue build 命令对单个 *.vue 文件进行快速原型开发，不过这需要先额外安装一个全局的扩展：
npm install -g @vue/cli-service-global
vue serve 的缺点就是它需要安装全局依赖，这使得它在不同机器上的一致性不能得到保证。因此这只适用于快速原型开发。
Usage: serve [options] [entry]
在开发环境模式下零配置为 .js 或 .vue 文件启动一个服务器
Options:
-o, --open 打开浏览器
-c, --copy 将本地 URL 复制到剪切板
-h, --help 输出用法信息
ue serve 使用了和 vue create 创建的项目相同的默认设置 (webpack、Babel、PostCSS 和 ESLint)。它会在当前目录自动推导入口文件——入口可以是 main.js、index.js、App.vue 或 app.vue 中的一个。你也可以显式地指定入口文件：
vue serve MyComponent.vue
详细使用方法你可以参考官方文档，作为初学者的我深试了多次，还是报错了，主要还是不理解 webpack 打包的原理，想想还是放弃了。
但是我想到 vue 是可以嵌入到 html 页面中的，这样的话，就不需要编译打包这么麻烦了，于是我尝试弄了一下，竟然成功了。
参考 vue ， element-ui 快速上手的例子，我把原来的 vue 文件转换成下面的 html 文件，先让界面显示出来，后续再加入 api 的实现 。
