vue 使用el-table循环轮播数据列表的实现

<template>
  <div>
    <el-table
      :data="devData"
      style="width: 100%">
      <el-table-column label="排名">
        <template slot-scope="scope">
          <span>第{{scope.$index +1}}名</span>
        </template>
      </el-table-column>
      <el-table-column
        prop="name"
        label="日期">
      </el-table-column>
      <el-table-column
        prop="scale"
        label="姓名">
      </el-table-column>
    </el-table>
  </div>
</template>

  }
