<template>
    <!-- bordered 表示表格中的边框
     pagination="false"不要分页 
  -->
    <a-table :data-source="dataSource" :columns="columns" :pagination="false">
        <template #operation="{ record }">
            <a class="">编辑</a>
            <a class="line-linela"></a>
            <a-popconfirm
                v-if="dataSource.length"
                title="Sure to delete?"
                @confirm="onDelete(record.key)"
            >
                <a>删除</a>
            </a-popconfirm>
        </template>
    </a-table>
