前期回顾
纯前端 —— 200行JS代码、实现导出Excel、支持DIY样式，纵横合并-CSDN博客https://blog.csdn.net/m0_57904695/article/details/135537511?spm=1001.2014.3001.5501
在平时开发中，系统中写的最多的 表格+搜索表单排名No.1，每一次都在Element-Plus中 拷贝一遍 <template> ,显然是个大活，我们将其html封装，每一只写Data数据让其动态渲染，编写速度达达滴！
一、🛠️ newTable.vue 封装Table
<template>
<div class="container">
<div class="container-main">
<!-- 表单搜索区域 -->
<el-scrollbar v-if="isShowSearchRegion" max-height="300px" class="scrollbar-height">
<slot name="search"></slot>
</el-scrollbar>
<!-- 表格上方搜索向下方按钮区域 -->
<slot name="btn"></slot>
<!-- 列表区域 -->
<el-table
ref="multipleTableRef"
v-bind="$attrs"
stripe
style="width: 100%"
:data="filterTableData"
:border="tableBorder"
:height="tableHeight || excludeSearchAreaAfterTableHeight"
:row-key="getRowKeys"
@selection-change="onSelectionChange"
>
<template #empty>
<el-empty :image-size="emptyImgSize" description="暂无数据" />
</template>
<el-table-column
type="selection"
width="30"
v-if="isSelection"
:reserve-selection="true"
:selectable="selectableCallback"
/>
<el-table-column
type="index"
label="序号"
min-width="60"
:index="orderHandler"

<el-table-column
v-for="item in tableHeader"

</template>
<template #default="{ row }" v-if="item.slotKey">
<slot
v-for="slot in item.slotKey.split(',')"
:name="slot"
:row="row"
></slot>
<template v-if="item.slotKey.includes('default')">
<el-link type="primary" :underline="false" @click="handleEdit(row)"
>编辑</el-link
>
<el-popconfirm title="确定删除吗？" @confirm="handleDelete(row.id)">
<template #reference>
<el-link type="danger" :underline="false">删除</el-link>
</template>
</el-popconfirm>
</template>
</template>
</el-table-column>
</el-table>
<!-- 分页区域-->

二、🚩 newForm.vue 封装搜索表单
<template>
<el-form ref="searchFormRef" :model="searchForm" size="default">
<!-- 使用了不稳定的 key，可能会导致一些不可预期的行为，比如输入框失去焦点。 -->
<el-row>
<el-col
:xs="24"
:sm="24"
:md="24"
:lg="12"
:xl="6"
v-for="item in formOptions"
:key="item.vm"
>
<el-form-item :label="item.props.label" :prop="item.vm">
<el-input
v-if="item.type === FormOptionsType.INPUT"
v-model.lazy.trim="searchForm[item.vm]"
v-bind="item.props"
class="ml10 w100"
></el-input>
<el-select
v-if="item.type === FormOptionsType.SELECT"
v-model.lazy="searchForm[item.vm]"
v-bind="item.props"
class="ml10 w100"
fit-input-width
>
<el-option label="全部" value=""></el-option>
<el-option
v-for="option in item.selectOptions"
:key="option.value"
:label="option.label"

v-model.lazy="searchForm[item.vm]"

v-bind="item.props"

<el-date-picker
v-if="item.type === FormOptionsType.DATE_PICKER"
v-model.lazy="searchForm[item.vm]"
v-bind="item.props"
class="ml10 w100"
/>
</el-form-item>
</el-col>
<el-col :xs="24" :sm="24" :md="24" :lg="12" :xl="6" class="xs-mt">
<el-form-item style="margin-left: 10px">
<el-button @click="onSearch('reset')">

查询
</el-button>
</el-form-item>
</el-col>
</el-row>
</el-form>
</template>
<script setup lang="ts" name="newForm">
import { toRefs, onBeforeUnmount, ref } from 'vue';
import type { PropType } from 'vue';
import { type FormInstance } from 'element-plus';
import { debounce } from '/@/utils/debounce';
const searchFormRef = ref<FormInstance>();
enum FormOptionsType {
INPUT = 'input', // 输入框
SELECT = 'select', // 下拉框
CASCADER = 'cascader', // 级联选择器
DATE_PICKER = 'date-picker', // 日期选择器
}
const props = defineProps({
formOptions: {
type: Array as PropType<FormOptions[]>,
required: true,
},
searchForm: {
type: Object as PropType<SearchFormType>,
required: true,
},
});
const { formOptions, searchForm } = toRefs(props);
const emit = defineEmits(['search']);
const debouncedEmitSearch = debounce((type) => emit('search', type));
const onSearch = (type: string) => {
if (type) searchFormRef.value?.resetFields();
debouncedEmitSearch(type);
};
onBeforeUnmount(() => searchFormRef.value?.resetFields());
defineExpose({ searchFormRef });
</script>
<style scoped lang="scss">
:deep(.el-form-item__label) {
margin-left: 10px;
}
</style>
<style scoped lang="scss">
:deep(.el-form-item__label) {
margin-left: 10px;
}
</style>
三、📝 TS类型 src\types\global.d.ts
// new-table
//表头数据类型定义
declare interface TableHeader<T = any> {
label: string;
prop: string;
align?: string;
overHidden?: boolean;
minWidth?: string;
sortable?: boolean;
type?: string;
fixed?: string;
width?: string | number;
// isActionColumn?: boolean; // 是否是操作列
// isCustomizeColumn?: boolean; // 是否是自定义列
slotKey?: string; // 自定义列的插槽名称
searchFields?: boolean; // 是否是搜索字段
}
/*
newForm
允许任何字符串作为索引
不然会报错, 使用动态属性名,需要使用索引签名
*/
declare type SearchFormType = {
[key: string]: string;
};
declare type FormOptions = {
type: string;
props: {
label: string;
placeholder: string;
type: string;
clearable: boolean;
};
vm: string;
selectOptions?: {
value: string | number;
label: string;
}[];
cascaderOptions?: any;
};
四、♻️ 页面使用功能 - 静态
<template>

:xl="6"
v-for="item in Math.ceil(Math.random() * 10)"
:key="item"
class="scrollbar-demo-item"
>56546</el-col

<el-col :xs="24" :sm="24" :md="24" :lg="12" :xl="6" class="xs-mt">
