6-3 电子书表格展示

Posted 2022-12-01 孤注一掷 、

在ant design 上寻找表格实例：

 代码如下：

<template>
  <a-table :columns="columns" :data-source="data">
    <template #name=" text ">
      <a> text </a>
    </template>
    <template #customTitle>
      <span>
        <smile-outlined />
        Name
      </span>
    </template>
    <template #tags=" text: tags ">
      <span>
        <a-tag
          v-for="tag in tags"
          :key="tag"
          :color="tag === 'loser' ? 'volcano' : tag.length > 5 ? 'geekblue' : 'green'"
        >
           tag.toUpperCase() 
        </a-tag>
      </span>
    </template>
    <template #action=" record ">
      <span>
        <a>Invite 一  record.name </a>
        <a-divider type="vertical" />
        <a>Delete</a>
        <a-divider type="vertical" />
        <a class="ant-dropdown-link">
          More actions
          <down-outlined />
        </a>
      </span>
    </template>
  </a-table>
</template>
<script>
import  SmileOutlined, DownOutlined  from '@ant-design/icons-vue';
import  defineComponent  from 'vue';
const columns = [
  
    dataIndex: 'name',
    key: 'name',
    slots: 
      title: 'customTitle',
      customRender: 'name',
    ,
  ,
  
    title: 'Age',
    dataIndex: 'age',
    key: 'age',
  ,
  
    title: 'Address',
    dataIndex: 'address',
    key: 'address',
  ,
  
    title: 'Tags',
    key: 'tags',
    dataIndex: 'tags',
    slots: 
      customRender: 'tags',
    ,
  ,
  
    title: 'Action',
    key: 'action',
    slots: 
      customRender: 'action',
    ,
  ,
];
const data = [
  
    key: '1',
    name: 'John Brown',
    age: 32,
    address: 'New York No. 1 Lake Park',
    tags: ['nice', 'developer'],
  ,
  
    key: '2',
    name: 'Jim Green',
    age: 42,
    address: 'London No. 1 Lake Park',
    tags: ['loser'],
  ,
  
    key: '3',
    name: 'Joe Black',
    age: 32,
    address: 'Sidney No. 1 Lake Park',
    tags: ['cool', 'teacher'],
  ,
];
export default defineComponent(
  setup() 
    return 
      data,
      columns,
    ;
  ,

  components: 
    SmileOutlined,
    DownOutlined,
  ,
);
</script>

其中：

 每个渲染都会起名字，如#name

下面，

 其中，dataIndex是属性，即表格的字段，一般与key同名即可。

slots：是渲染，这里是渲染customTitle，针对表头的渲染。

这里的tag，用customRender对于值的渲染。

下面看tags。

加了一个边框，加了一个底色

 tags是一个数组。

效果如下：

 下面来改布局：

admin-ebook.vue中修改为：

<template>
  <a-layout>
    <a-layout-content
        :style=" background: '#fff', padding: '24px', margin: 0, minHeight: '280px' "
    >
      <a-table
          :columns="columns"
          :row-key="record => record.id"
          :data-source="ebooks"
          :pagination="pagination"
          :loading="loading"
          @change="handleTableChange"
      >
        <template #cover=" text: cover ">
          <img v-if="cover" :src="cover" alt="avatar" />
        </template>
        <template v-slot:action=" text, record ">
          <a-space size="small">
            <a-button type="primary">
              编辑
            </a-button>
            <a-button type="danger">
              删除
            </a-button>
          </a-space>
        </template>
