基于antd+vue2来实现一个简单的绘画流程图功能

简单流程图的实现（基于antd+vue2的）代码很多哦~
实现页面如下

1.简单操作如下

2.弹框中使用组件：

 	<vfd
      ref="vfd"
      style="background-color: white;"
      :needShow="true"
      :fieldNames="fieldNames"
      @openUser="openUser"
      @openRole="openRole"
    ></vfd>

8

3.组件的文件结构：

FlowDesigner.vue代码如下

<template>
  <div style="height: 60vh">
    <a-layout class="container">
      <a-layout-sider
        v-show="needShow"
