element 怎么去控制每一行的 switch 狀態(tài)

怎么根據(jù)后端返回值 去控制每一行的狀態(tài)？ 主要是怎么控制每一行？ 直接寫scope.row.on 報(bào)錯(cuò)scope，拿不到

       this.$get('/api/shop', this.getDate).then(res => {
          console.log(this.scope); //undefined     
          console.log(scope);      //scope is not defined
      }



      <el-table-column width="200%" label="狀態(tài)" class="switchVal">
        <template slot-scope="scope">
          <el-switch
            @change="changeSwitch(scope.$index, scope.row)"
            v-model="scope.row.on"
            active-text="啟用"
            inactive-text="">
            on-color="#00A854"
            on-text="啟動(dòng)"
            on-value="1"
            off-color="#F04134"
            off-text="禁止"
            off-value="0"
            >
          </el-switch>
        </template>
      </el-table-column>
      
      
      
      
   changeSwitch(index, row) {
    if (row.on) {
      this.$confirm('是否確認(rèn)啟用', '提示', {
        confirmButtonText: '確定',
        cancelButtonText: '取消',
        type: 'warning'
      }).then(() => {
        row.on = true
      }).catch(() => {
        row.on = false
      });
    }else {
      this.$confirm('禁用后，該商戶的前臺(tái)頁面將無法正常訪問，是否確認(rèn)禁用？', '提示', {
        confirmButtonText: '確定',
        cancelButtonText: '取消',
        type: 'warning'
      }).then(() => {
        row.on = false
      }).catch(() => {
        row.on = true
      });
    }
  },
