在antd组件库中的使用示例：

<template>
  <a-button class="editable-add-btn" style="margin-bottom: 8px" @click="handleAdd">Add</a-button>
  <a-table bordered :data-source="dataSource" :columns="columns">
    <template #bodyCell="{ column, text, record }">
      <template v-if="column.dataIndex === 'name'">
        <div class="editable-cell">
          <div v-if="editableData[record.key]" class="editable-cell-input-wrapper">
            <a-input v-model:value="editableData[record.key].name" @pressEnter="save(record.key)" />
            <check-outlined class="editable-cell-icon-check" @click="save(record.key)" />
          </div>
          <div v-else class="editable-cell-text-wrapper">
            {{ text || ' ' }}
            <edit-outlined class="editable-cell-icon" @click="edit(record.key)" />
          </div>
        </div>
      </template>
      <template v-else-if="column.dataIndex === 'operation'">
        <a-popconfirm
            v-if="dataSource.length"
            title="Sure to delete?"
            @confirm="onDelete(record.key)"
        >
          <a>Delete</a>
        </a-popconfirm>
      </template>
    </template>
  </a-table>
