Vueはdivローラー拡大縮小を実現しました。

Vueプロジェクトの中でdivローラーの拡大縮小を実現して、ドラッグ効果、キャンバス効果のようです。

1、プラグインvue-draggable-resizableを導入し、ポイントはGitHubアドレスに入ります。
1）、npm install--save vue-dragable-resizable
2）、main.jsファイルで
import Vue Draggable Resizable from'vue-dragable-resizable'
import'vue-draggable-resizable/dist/Vue Draggableble.css'
Vue.com onent('vue-dragable-resizable'，Vue Draggable Resizable)
3）、vueファイルで使用する
main.js：

import Vue from 'vue'
import App from './App'
import router from './router'
Vue.config.productionTip = false

// iview
import ViewUI from 'view-design';
import 'view-design/dist/styles/iview.css';
Vue.use(ViewUI)

//   ・  ・    
import VueDraggableResizable from 'vue-draggable-resizable'
import 'vue-draggable-resizable/dist/VueDraggableResizable.css'
Vue.component('vue-draggable-resizable', VueDraggableResizable)

new Vue({
  el: '#app',
  router,
  components: { App },
  template: '<App/>'
})

vueファイル：コンポーネントvue-dragable-resizableの配置項目とhandleTable Wheel、tableZoomの導入方法に注目すればいいです。
