row即为接口返回的当前行的数据
<el-table-column label="表头">
<template slot-scope="scope">
<div v-for="item in scope.row.technicalContacts" :key="item.phone">
<div>{{item.phone}}</div>
</div>
</template>
</el-table-column>
如果要使用当前行的索引可以这样做
<el-table-column prop="date" label="头" width="50">
<template slot-scope="scope">
<div>
{{ scope.$index + 1 }}
</div>
</template>
</el-table-column>
