### icon
use [font Awesome](https://fontawesome.com/),also you can use other UI components icon,for example [elementUI](http://element-cn.eleme.io/).And add the icon class to "icoName". if you set like (icoName: 'el-icon-delete'), that will be add a "Trash" to your page.
you can add the style file into html like this:
```
<link href="//netdna.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css" rel="stylesheet">
```
also if you use like elementUI, maybe you can use by
```
   import 'element-ui/lib/theme-chalk/index.css';
```
