vxe-table 是vue中非常强大的表格,公司项目中复杂的渲染都是用 vxe-table 的,对于用的排序。筛选之类的都能支持,而且也能任意扩展,非常强大。
默认筛选功能
筛选的普通用法就是给对应的列指定参数: filters:[] 选项数组
<template>
<div>
<vxe-table
border
height="400"
:data="tableData">
<vxe-column field="id" title="ID"></vxe-column>
<vxe-column field="name" title="Name" ></vxe-column>
<vxe-column field="sex" title="Sex" :filters="sexOptions" :filter-multiple="false"></vxe-column>
<vxe-column field="age" title="Age" :filters="ageOptions"></vxe-column>
<vxe-column field="time" title="Time"></vxe-column>
</vxe-table>
</div>
</template>
<script setup>
import { ref } from 'vue'
const tableData = ref([
{ id: 10001, name: 'Test1', role: 'Develop', sex: 'Man', age: 28, address: 'test abc' },
{ id: 10002, name: 'Test2', role: 'Test', sex: 'Women', age: 22, address: 'Guangzhou' },
{ id: 10003, name: 'Test3', role: 'PM', sex: 'Man', age: 32, address: 'Shanghai' },
{ id: 10004, name: 'Test4', role: 'Designer', sex: 'Women', age: 24, address: 'Shanghai' }
])
const sexOptions = ref([
{ label: 'Man', value: '1' },
{ label: 'Woman', value: '0' }
])
const ageOptions = ref([
{ label: '28', value: 28 },
{ label: '22', value: 22 },
{ label: '38', value: 38 }
])
</script>
进阶扩展
上面看了普通用法,接下就详细讲一下扩展高级用法,这就涉及到渲染器了。筛选需要用法渲染的几个方法:
showTableFilterFooter // 是否显示筛选底部,可以关闭, 使用自定义底部
renderTableFilter // 自定义筛选模板
tableFilterResetMethod // 自定义重置数据方法
tableFilterRecoverMethod / 自定义重置筛选复原方法(当未点击确认时,该选项将被恢复为默认值)
tableFilterMethod // 自定义筛选方法
接下来就可以实现
定义渲染器
定义渲染器文件:src/plugins/vxe/render.jsx
// main.js
import { VxeUI } from 'vxe-table';
import FilterComplex from './filters/FilterComplex.vue';
// 创建一个带条件的筛选渲染器
VxeUI.renderer.add('MyTableFilterComplex', {
// 不显示底部按钮,使用自定义的按钮
showTableFilterFooter: false,
// 自定义筛选模板
renderTableFilter(renderOpts, params) {
return <FilterComplex params={params} />;
},
// 自定义重置数据方法
tableFilterResetMethod(params) {
const { options } = params;
options.forEach((option) => {
option.data = { type: 'has', name: '' };
});
},
// 自定义筛选数据方法
tableFilterMethod(params) {
const { option, row, column } = params;
const cellValue = row[column.field];
const { name, type } = option.data;
if (cellValue) {
if (type === 'has') {
return cellValue.indexOf(name) > -1;
}
return cellValue === name;
}
return false;
}
})
创建文件筛选面板组件:src/plugins/vxe/filters/FilterComplex.vue
<template>
<div v-if="currOption" class="my-filter-complex">
<div class="my-fc-type">
<VxeRadio v-model="currOption.data.type" name="fType" label="has">包含</VxeRadio>
<VxeRadio v-model="currOption.data.type" name="fType" label="eq">等于</VxeRadio>
</div>
<div class="my-fc-name">
<VxeInput v-model="currOption.data.name" class="my-fc-input" mode="text" placeholder="请输入名称" @input="changeOptionEvent()"></VxeInput>
</div>
<div class="my-fc-footer">
<VxeButton @click="resetEvent">重置</VxeButton>
<VxeButton status="primary" @click="confirmEvent">确认</VxeButton>
</div>
</div>
</template>
<script setup>
import { watch, ref } from 'vue'
const props = defineProps({
params: {
type: Object,
default: () => ({})
}
})
const currOption = ref()
const load = () => {
const { params } = props
if (params) {
const { column } = params
const option = column.filters[0]
currOption.value = option
}
}
const changeOptionEvent = () => {
const { params } = props
const option = currOption.value
if (params && option) {
const { $panel } = params
const checked = !!option.data.name
$panel.changeOption(null, checked, option)
}
}
const confirmEvent = () => {
const { params } = props
if (params) {
const { $panel } = params
$panel.confirmFilter()
}
}
const resetEvent = () => {
const { params } = props
if (params) {
const { $panel } = params
$panel.resetFilter()
}
}
watch(() => {
const { column } = props.params || {}
return column
}, load)
load()
</script>
<style lang="scss" scoped>
.my-filter-complex {
width: 260px;
padding: 5px 15px 10px 15px;
.my-fc-type {
padding: 8px 0;
}
.my-fc-input {
width: 100%;
}
.my-fc-footer {
text-align: center;
margin-top: 8px;
}
}
</style>
src/main.js 中全局引入渲染器:
// ...
import VxeUI from 'vxe-pc-ui'
import 'vxe-pc-ui/lib/style.css'
import VxeUITable from 'vxe-table'
import 'vxe-table/lib/style.css'
// ...
import './plugins/vxe/render'
createApp(App).use(VxeUI).use(VxeUITable).mount('#app')
// ...
然后使用
通过 filter-render={ name: 'MyTableFilterComplex' } 指定 name 就可以调用渲染器,其中 name 就是自定义的渲染器名称。
