解析 mysql create table 语句，用于通过建表语句生成 model 代码文件。

```
yarn install @mmzp/sql-parser
yarn dev
```

或

```
npm i @mmzp/sql-parser
npm run dev
```

```
// 构建支持浏览器环境的代码文件，浏览器端直接引用构建出来的 browser/sql-parser.min.js 文件即可，browser/demo.html 为调用示例

yarn browser
或
npm run browser
```

[在线示例 https://mmzp.github.io/sql-parser/browser/demo.html](https://mmzp.github.io/sql-parser/browser/demo.html)

解析结果如下：
