elementui 点击table的一行数据,怎么更改这一行的样式?

我是绑定row-click点击事件,获取row的参数,修改它。
table的row-class-name 没有触发更新,怎么回事?
row里的数据没有被绑定上去?

想实现的效果就是点击一行数据,就修改这一行的样式。

官方demo,应该没问题吧~

<template>
  <el-table
    :data="tableData"
    style="width: 100%"
    :row-class-name="tableRowClassName">
    <el-table-column
      prop="date"
      label="日期"
      width="180">
    </el-table-column>
    <el-table-column
      prop="name"
      label="姓名"
      width="180">
    </el-table-column>
    <el-table-column
      prop="address"
      label="地址">
    </el-table-column>
  </el-table>
</template>

<style>
  .el-table .warning-row {
    background: oldlace;
  }

  .el-table .success-row {
    background: #f0f9eb;
  }
</style>

<script>
  export default {
    methods: {
      tableRowClassName({row, rowIndex}) {
        if (rowIndex === 1) {
          return 'warning-row';
        } else if (rowIndex === 3) {
          return 'success-row';
        }
        return '';
      }
    },
    data() {
      return {
        tableData: [{
          date: '2016-05-02',
          name: '王小虎',
          address: '上海市普陀区金沙江路 1518 弄',
        }, {
          date: '2016-05-04',
          name: '王小虎',
          address: '上海市普陀区金沙江路 1518 弄'
        }, {
          date: '2016-05-01',
          name: '王小虎',
          address: '上海市普陀区金沙江路 1518 弄',
        }, {
          date: '2016-05-03',
          name: '王小虎',
          address: '上海市普陀区金沙江路 1518 弄'
        }]
      }
    }
  }
</script>
