## 1 修改element.js ##

import Vue from 'vue'
    // 按需分配各个组件
    import {
        Button,
        Form,
        FormItem,
        Input,
        Message,
        Container,
        Header,
        Aside,
        Main,
        Menu,
        Submenu,
        MenuItem,
        Breadcrumb,
        BreadcrumbItem,
        Card,
        Row,
        Col,
        Table,
        TableColumn,
        Switch,
        Tooltip,
        Pagination,
        Dialog,
        MessageBox
    } from 'element-ui'
    
    
    Vue.use(Button)
    Vue.use(Form)
    Vue.use(FormItem)
    Vue.use(Input)
    Vue.use(Container)
    Vue.use(Header)
    Vue.use(Aside)
    Vue.use(Main)
    Vue.use(Menu)
    Vue.use(Submenu)
    Vue.use(MenuItem)
    Vue.use(Breadcrumb)
    Vue.use(BreadcrumbItem)
    Vue.use(Card)
    Vue.use(Row)
    Vue.use(Col)
    Vue.use(Table)
    Vue.use(TableColumn)
    Vue.use(Switch)
    Vue.use(Tooltip)
    Vue.use(Pagination)
    Vue.use(Dialog)
    // 这里和其他组件不一样，需要通过 prototype 全局挂载 Message
    Vue.prototype.$message = Message
    Vue.prototype.$confirm = MessageBox.confirm

## 2 修改 Users.vue ##
