通常我们使用一个table 来渲染服务的返回来的数据时，数据结构一般都是按row 来返回的，并且表头也是固定的
但是如果接口返回的数据结构不是我们想要的，表头也不确定时，我们该如何解析数据，将数据进行二次加工，转换成为我们想要的数据结构
下面是一个例子，其中tableData 就是返回的数据，是按列返回的，我们通过遍历数据把它转化为行数据结构：
<template>
<div id="app">
<el-table :data="data_" border style=" 100%" align='center'>
<el-table-column label="项目/机构" prop="name" align='center'></el-table-column>
<el-table-column
align='center'
v-for="(item, index) in thead"
:key="index" :label="item"
:prop="item">
</el-table-column>
</el-table>
</div>
</template>
