一个vue-table的组件

说明：

1.基于element-ui开发的vue表格组件。

功能:

1.支持树形数据的展示

2.行拖拽排序

3.单元格拖拽排序

github

使用方法：

1.下载npm包:

你的VUE项目的根目录底下运行：

    npm install ele-table
```

2.引入本npm包并注册为vue的组件：

例如：在需要使用的vue页面中：

```<template>

    <!-- 里面写ele-table组件-->
    <ele-table :data="tableData" treetable style="width: 100%">
      <ele-table-column prop="id" label="姓名">
        <template slot-scope="scope">
          <div :style="`padding-left:${20*(scope.row._indent-1)}px`">
            <span  v-if="scope.row.children">
              <i v-if="scope.row._expand" >-</i><i v-else>+</i>
            </span>
            <span>{{scope.row.id}}</span>
          </div>
        </template>
      </ele-table-column>
      <ele-table-column prop="id" label="年龄" width="180">
      </ele-table-column>
      <ele-table-column
        prop="label"
        label="地址">
      </ele-table-column>
    </ele-table>
    <ele-table
      draggablerow //能否行拖拽
      :allow-drag="allowdrag" //能否被拖拽
      :allow-drop="allowDrop" //能否被放置
      :data="tableData"
      @node-drag-start="handleDragStart"
      @node-drag-enter="handleDragEnter"
      @node-drag-leave="handleDragLeave"
      @node-drag-over="handleDragOver"
      @node-drag-end="handleDragEnd"
      style="width: 100%">
      <ele-table-column prop="id" label="姓名"   width="180">
      </ele-table-column>
      <ele-table-column
        prop="id"
        label="年龄"
        width="180">
      </ele-table-column>
      <ele-table-column
        prop="label"
        label="地址">

    </ele-table>
