Vue.use(Upload)
// 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

5 修改global.css

/* 全局样式 */
/* 撑满全屏 */
html, body, #app {
    height: 100%;
    margin: 0;
    padding: 0;
}

.el-breadcrumb {
    margin-bottom: 15px;
    font-size: 12px;
}

/* 设置卡片阴影 */
.el-card {
    box-shadow: 0 1px 1px rgba(0, 0, 0, 0.15) !important;
}

.el-table {
    margin-top: 15px;
    font-size: 12px;
}

.el-pagination {
    margin-top: 15px;
}

.el-tag {
    margin: 7px;
}

.bdtop {
    border-top: 1px solid #eee;
}

.bdbottom {
    border-bottom: 2px solid #eee;
}
.el-steps{
    margin: 15px 0;
}
.el-step__title{
    font-size: 13px;
}
.ql-editor{
    min-height: 300px;
}

6 修改 main.js

import Vue from 'vue'
import App from './App.vue'
import router from './router'
import './plugins/element.js'
// 导入阿里的字体图标
import './assets/fonts/iconfont.css'
// 导入全局样式表,使得全局样式生效
import './assets/css/global.css'
// 全局导入axios
import axios from 'axios'
// 导入TreeTable 插件
import TreeTable from 'vue-table-with-tree-grid'
// 导入富文本编辑器组件
import VueQuillEditor from 'vue-quill-editor'
// 导入富文本编辑器对应的样式
import 'quill/dist/quill.core.css' // import styles
import 'quill/dist/quill.snow.css' // for snow theme
import 'quill/dist/quill.bubble.css' // for bubble theme

// 设置axios请求的根路径
axios.defaults.baseURL = 'http://127.0.0.1:8888/api/private/v1/'
// axios请求拦截
axios.interceptors.request.use(config => {
    // 为请求头对象，添加 Token 验证的 Authorization 字段
    config.headers.Authorization = window.sessionStorage.getItem('token')
    return config
})
Vue.prototype.$http = axios


Vue.config.productionTip = false
// 注册 TreeTable 组件
Vue.component('tree-table', TreeTable)
// 注册 富文本编辑器 组件为全局可用组件
Vue.use(VueQuillEditor)
// 添加时间过滤器
Vue.filter('dateFormat', function (originVal) {
    const dt = new Date(originVal)

    const y = dt.getFullYear()
    const m = (dt.getMonth() + 1 + '').padStart(2, '0')
    const d = (dt.getDate() + '').padStart(2, '0')
    const hh = (dt.getHours() + '').padStart(2, '0')
    const mm = (dt.getMinutes() + '').padStart(2, '0')
    const ss = (dt.getSeconds() + '').padStart(2, '0')

    return `${y}-${m}-${d} ${hh}:${mm}:${ss}`

})

new Vue({
    router,
    render: h => h(App)
}).$mount('#app')

三 效果
