# 安装Element-ui #

npm i element-ui -S

# 引入 Element-ui #

在 main.js 文件里引入并注册 ( 这里是 Vue3.0 的模板 )

import Vue from 'vue'
    import App from './App.vue'
    import router from './router'
    import store from './store'
    
    import 'element-ui/lib/theme-chalk/index.css'
    import '../public/css/iconfont.css' // 引入字体图标样式
    import '../public/css/reset.css' // 引入初始化样式
    
    import ElementUI from 'element-ui' // 引入element-ui
    
    Vue.use(ElementUI)
    
    Vue.config.productionTip = false
    
    new Vue({ 
      router,
      store,
      render: h => h(App)
    }).$mount('#app')

# 在组件中使用Element-ui #

####     第一种方式：作用域槽头，推荐使用 ####

####     第二种方式：会报警告，不会阻塞代码运行 ####

\[Element Warn\]\[TableColumn\]Comparing to render-header, scoped-slot header is easier to use. We recommend users to use scoped-slot header.  
    \[Element Warn\]\[TableColumn\]与呈现头相比，作用域槽头更易于使用。我们建议用户使用作用域槽头。
