理解vue中的 slot-scope=scope

slot是插槽，slot-scope=“scope“语义更加明确，相当于一行的数据，在实际开发中会碰到如下的场景，

页面上的头衔列是变化的，而我们就可以通过后端返回的具体值来判断这里应该显示什么样的内容，具体代码如下

<template>
    <div class="login-container">
      讲师列表
      <el-table
      :data="list"
      style="width: 100%"
      border
      fit
      highlight-current-row
      element-loading-text="数据加载中"
      
    >
      <el-table-column prop="date" label="序号" width="70" align="center">
        <template slot-scope="scope">
          {{ (page - 1) * limit + scope.$index + 1 }}
        </template>
      </el-table-column>
      <el-table-column prop="name" label="名称" width="80"> </el-table-column>
      <el-table-column label="头衔" width="80">
        <template slot-scope="scope">
          {{ scope.row.level === 1 ? "高级讲师" : "首席讲师" }}
        </template>
      </el-table-column>
      <el-table-column prop="intro" label="资历" />
      <el-table-column prop="gmtCreate" label="添加时间" width="160" />
      <el-table-column prop="sort" label="排序" width="60" />
      <el-table-column label="操作" width="200" align="center">
        <template slot-scope="scope">
          <router-link :to="'/edu/teacher/edit/' + scope.row.id">
            <el-button type="primary" size="mini" icon="el-icon-edit"
              >修改</el-button
            >
          </router-link>
          <el-button
            type="danger"
            size="mini"
            icon="el-icon-delete"
            @click="removeDataById(scope.row.id)"
            >删除</el-button
          >
        </template>
      </el-table-column>
    </el-table>
    </div>
</template>
