element-UI中table表格的row-click事件怎么获取一行数据的id

<el-table :data="tableData" style="width: 100%" @row-click="openDetails(id)">
  <el-table-column prop="wName" label="公众号名称"></el-table-column>
  <el-table-column prop="wID" label="公众号ID"></el-table-column>
  <el-table-column prop="seller" label="商家名称"></el-table-column>
  <el-table-column prop="sign" label="签约状态"></el-table-column>
  <el-table-column prop="amount_1" label="收款总额"></el-table-column>
  <el-table-column prop="amount_2" label="退款总额"></el-table-column>
  <el-table-column prop="amount_3" label="代收总额"></el-table-column>
  <el-table-column prop="amount_4" label="保证金"></el-table-column>
  <el-table-column prop="date" label="签约日期"></el-table-column>
  <el-table-column prop="status" label="状态"></el-table-column>
</el-table>

该如何把一行数据的id放到@row-click里面看成参数传递呢？

export default { data () { return { tableData: [ { id: '1', wName: 'xxx公众号1', wID: 'zjfiawsf', seller: 'xxxxx公司xxxxx公司xxxxx公司', sign: '已签约', amount_1: '14614.00', amount_2: '0.00', amount_3: '322.00', amount_4: '32122.00', date: '2019-08-09', status: '未冻结' }, { id: '2', wName: 'xxx公众号2', wID: 'zjfiawsf', seller: 'xxxxx公司xxxxx公司xxxxx公司', sign: '已签约', amount_1: '14614.00', amount_2: '0.00', amount_3: '322.00', amount_4: '32122.00', date: '2019-08-09', status: '未冻结' } ] } }, methods: { //打开详情页弹窗 openDetails(id) { console.log(id) }, } }

// 文档中有：row-click 当某一行被点击时会触发该事件 三个参数：row, event, column methods: { //打开详情页弹窗 openDetails(row) { console.log(row.id); }, }

row-click返回了三个参数 row, event, column

row-click 当某一行被点击时会触发该事件 row, event, column
在做用域中没有id这个变量，全部点击行会报错。
不该该传递参数，element自己对row-click这个事件自动注入了必要的参数(row, event, column)，若传入的openDetails原理是注册一个钩子回调而已。
