    meta: { title: '课程分类管理', icon: 'suject' },
    children: [
      {
        path: 'list',
        name: '课程分类列表',
        component: () => import('@/views/edu/teacher/list'),
        meta: { title: '讲师列表', icon: 'table' }
      },
      {
        path: 'save',
        name: '添加课程分类',
        component: () => import('@/views/edu/teacher/save'),
        meta: { title: '添加课程分类', icon: 'tree' }
      },

    ]

<script>
