vxe-table 通过配置 ajax 方式自动请求数据，适用于简单场景的列表
当系统中很多页面都是简单列表时，每次都要手动去请求接口后再赋值，过程就会比较冗余繁琐。解决方式一般就是将封装一下。本章的方式是通过 vxe-grid 配置 ajax 来实现自动请求加载数据，无需封装组件，适用于通用简单列表。

普通列表

通过 proxy-config.ajax.query 配置查询接口

<template>
  <div>
    <vxe-grid v-bind="gridOptions"></vxe-grid>
  </div>
</template>

<script lang="ts" setup>
import { reactive } from 'vue'
import type { VxeGridProps } from 'vxe-table'

interface RowVO {
  id: number
  name: string
  nickname: string
  role: string
  sex: string
  age: number
  address: string
}

// 模拟后台接口
const findList = () => {
  console.log('调用查询接口')
  return new Promise<RowVO[]>(resolve => {
    setTimeout(() => {
      const list = [
        { id: 10001, name: 'Test1', nickname: 'T1', role: 'Develop', sex: 'Man', age: 28, address: 'Shenzhen' },
        { id: 10002, name: 'Test2', nickname: 'T2', role: 'Test', sex: 'Women', age: 22, address: 'Guangzhou' },
        { id: 10003, name: 'Test3', nickname: 'T3', role: 'PM', sex: 'Man', age: 32, address: 'Shanghai' },
        { id: 10004, name: 'Test4', nickname: 'T4', role: 'Designer', sex: 'Women', age: 23, address: 'test abc' },
        { id: 10005, name: 'Test5', nickname: 'T5', role: 'Develop', sex: 'Women', age: 30, address: 'Shanghai' },
        { id: 10006, name: 'Test6', nickname: 'T6', role: 'Designer', sex: 'Women', age: 21, address: 'Shenzhen' },
        { id: 10007, name: 'Test7', nickname: 'T7', role: 'Test', sex: 'Man', age: 29, address: 'Shenzhen' },
        { id: 10008, name: 'Test8', nickname: 'T8', role: 'Develop', sex: 'Man', age: 35, address: 'test abc' },
        { id: 10009, name: 'Test9', nickname: 'T9', role: 'Develop', sex: 'Man', age: 35, address: 'Shenzhen' },
        { id: 100010, name: 'Test10', nickname: 'T10', role: 'Develop', sex: 'Man', age: 35, address: 'Guangzhou' }
      ]
      resolve(list)
    }, 300)
  })
}

const gridOptions = reactive<VxeGridProps<RowVO>>({
  border: true,
  height: 500,
  proxyConfig: {
    // showLoading: false, // 关闭加载中
    ajax: {
      query: () => {
        // 默认接收 Promise<RowVO[]>
        return findList()
      }
    }
  },
  columns: [
    { type: 'seq', width: 70 },
    { field: 'name', title: 'Name' },
    { field: 'nickname', title: 'Nickname' },
    { field: 'role', title: 'Role' },
    { field: 'address', title: 'Address', showOverflow: true }
  ]
})

分页列表

分页查询跟列表查询的配置是一模一样的，区别就是多加一个分页配置项 page-config，以及接口响应结果带分页信息

<template>
  <div>
    <vxe-grid v-bind="gridOptions"></vxe-grid>
  </div>
</template>

<script lang="ts" setup>
import { reactive } from 'vue'
import type { VxeGridProps } from 'vxe-table'

interface RowVO {
  id: number
  name: string
  nickname: string
  role: string
  sex: string
  age: number
  address: string
}

const list = [
  { id: 10001, name: 'Test1', nickname: 'T1', role: 'Develop', sex: 'Man', age: 28, address: 'Shenzhen' },
  { id: 10002, name: 'Test2', nickname: 'T2', role: 'Test', sex: 'Women', age: 22, address: 'Guangzhou' },
  { id: 10003, name: 'Test3', nickname: 'T3', role: 'PM', sex: 'Man', age: 32, address: 'Shanghai' },
  { id: 10004, name: 'Test4', nickname: 'T4', role: 'Designer', sex: 'Women', age: 23, address: 'test abc' },
