<template slot-scope="scope">
            <el-switch
              v-model="scope.row.status"
              :active-value="1"
              :inactive-value="0"
              @change="changeStatus($event,scope.row.status)"
            >
            </el-switch>
        </template>

@change暂时没有用到所有只做了打印操作

changeStatus (val, state) {
      console.log(val, state)
    }

Q.E.D.
