# 9.9 数据展示组件
|
||
|
||
:::tip 概述
|
||
本节介绍前端项目中常用的数据展示组件,包括表格(BasicTable)、页面容器(PageWrapper)和图标选择器(IconPicker)。
|
||
:::
|
||
|
||
## Table 表格组件
|
||
|
||
```vue
|
||
<template>
|
||
<BasicTable
|
||
:columns="columns"
|
||
:request="loadDataTable"
|
||
:row-key="(row) => row.id"
|
||
ref="tableRef"
|
||
:actionColumn="actionColumn"
|
||
@update:checked-row-keys="onCheckedRow"
|
||
/>
|
||
</template>
|
||
|
||
<script setup>
|
||
import { h, reactive } from 'vue';
|
||
import { TableAction } from '@/components/Table';
|
||
import { getExamplePage } from '@/api/tool/example';
|
||
import { columns } from './columns';
|
||
|
||
// 分页请求函数(返回 {records, total, current, size, pages})
|
||
const loadDataTable = (params) => getExamplePage(params);
|
||
|
||
// 操作列(render 返回 TableAction,auth 控制按钮权限)
|
||
const actionColumn = reactive({
|
||
width: 200,
|
||
title: '操作',
|
||
key: 'action',
|
||
fixed: 'right',
|
||
render(record) {
|
||
return h(TableAction as any, {
|
||
actions: [
|
||
{ label: '编辑', type: 'info', onClick: () => handleEdit(record), auth: ['sys:example:update'] },
|
||
{ label: '删除', type: 'error', onClick: () => handleDelete(record), auth: ['sys:example:delete'] },
|
||
],
|
||
});
|
||
},
|
||
});
|
||
|
||
// 多选变化(勾选行 key 集合)
|
||
function onCheckedRow(keys) {
|
||
selectedKeys.value = keys;
|
||
}
|
||
</script>
|
||
```
|
||
|
||
:::tip 分页字段约定
|
||
本项目 `BasicTable` 通过 `:request` 传入分页请求函数(没有 `useTable` hook),内部绑定后端固定分页结构 `data.records` / `data.total`。`statusText` 等 `*Text` 字段由后端 `serializeMaps` 自动补全,直接作为列 `key` 使用即可。
|
||
:::
|
||
|
||
### 列定义常用属性
|
||
|
||
| 属性 | 说明 | 示例 |
|
||
|------|------|------|
|
||
| `title` | 列标题 | `'创建时间'` |
|
||
| `key` | 字段名(camelCase,与响应一致) | `'createTime'` |
|
||
| `width` / `minWidth` | 固定宽度 / 最小宽度(自适应) | `180` |
|
||
| `fixed` | 固定列:`left` / `right` | `'right'` |
|
||
| `type` | 列类型:`selection`(多选框)/ `index`(序号) | `'selection'` |
|
||
| `render` | 自定义渲染函数,参数为当前行对象 | `(record) => h(...)` |
|
||
| `auth` | 按权限控制列显示 | `['sys:example:update']` |
|
||
|
||
## Page 页面容器
|
||
|
||
```vue
|
||
<template>
|
||
<PageWrapper>
|
||
<!-- 页面内容 -->
|
||
</PageWrapper>
|
||
</template>
|
||
|
||
<script setup>
|
||
import { PageWrapper } from '@/components/Page';
|
||
</script>
|
||
```
|
||
|
||
## Icon 图标选择器
|
||
|
||
```vue
|
||
<template>
|
||
<IconPicker v-model="formData.icon" />
|
||
</template>
|
||
|
||
<script setup>
|
||
import IconPicker from '@/components/icon/picker.vue';
|
||
</script>
|
||
```
