利用Vue-draggable组件实现Vue项目中表格内容的拖拽排序

export default {
 components: {
 draggable,

<table class="dataTabble">
 <thead>
 <tr>
  <th width="110">栏目名称</th>

  <th width="160">公告数量</th>
  <th width="160">操作</th>

  <td>
  <div class="tabopa">
   <a @click="dialogFormVisible = true" style="cursor:pointer">添加</a>
   <a @click="open2">删除</a>

  </td>
 </tr>
