要实现一键保存，可以在页面中添加一个按钮，然后在点击该按钮时，遍历 `editableData` 数组，将数组中每个元素的修改后的值更新到 `dataSource` 数组中对应的元素上。

具体实现步骤如下：

1. 在页面中添加一个“保存”按钮，绑定点击事件 `handleSave`。

2. 在 `handleSave` 方法中，遍历 `editableData` 数组，将每个元素的修改后的值更新到 `dataSource` 数组中对应的元素上。

3. 更新 `dataSource` 数组后，清空 `editableData` 数组，使得页面上的所有输入框都变成文本展示。

下面是代码示例：

<template>
  <div>
    <a-table :pagination="false" :columns="columns" :dataSource="dataSource">
      <!-- //循环展示数据或input输入框 -->
      <template v-for="col in ['abbreviation', 'fullName', 'nodes']" :slot="col" slot-scope="text, record, index">
        <div :key="col">
          <a-input v-if="editableData[record.key]" v-model="editableData[record.key][col]" />
          <template v-else>{{ text }}</template>
        </div>
      </template>
      <!-- //操作 -->
      <template slot="operation" slot-scope="text, record, index">
        <span v-if="editableData[record.key]">
          <a-icon type="check" @click="save(record.key)" />
        </span>
        <span v-else>
          <a-icon type="delete" @click="deleteItem(record.key)" />
          <a-icon type="edit" @click="edit(record.key)" />
          <a-icon type="plus" v-if="index == dataSource.length - 1" @click="addItem(record.key)" />
        </span>
      </template>
    </a-table>
    <div>
      <a-button type="primary" @click="handleSave">保存</a-button>
      <a-button type="default" @click="handleCancel">取消</a-button>
    </div>
  </div>
</template>
