📚测试代码正常跑通，附其他基本代码

• 添加路由
• 页面展示入口

📘编写路由 src\router\index.js

import {
    createRouter, createWebHistory } from 'vue-router'
import RightClickMenuView from '../views/RightClickMenuView.vue'
import RangePickerView from '../views/RangePickerView.vue'


const router = createRouter({
   
  history: createWebHistory(import.meta.env.BASE_URL),
  routes: [
    {
   
      path: '/',
      name: 'progress',
      component:  () => import('../views/ProgressView.vue'),
    },
    {
   
      path: '/tabs',
      name: 'tabs',
      // route level code-splitting
      // this generates a separate chunk (About.[hash].js) for this route
      // which is lazy-loaded when the route is visited.
      // 标签页（Tabs）
      component: () => import('../views/TabsView.vue'),
    },
    {
   
      path: '/accordion',
