element+vue的table中某一行标红 ，标红指定行可以参考禁用selection某一行

      <el-table
        :row-class-name="tableRowClassName"
        -------------------------->

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

</style>

  //标红table第一行
      tableRowClassName({row, rowIndex}) {
        if (rowIndex === 0) {
          return 'warning-row';
        }
        return '';
      },
