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
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=" 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=" 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-column>
</ele-table>
</template>
