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"
					align="center"
				/>

				<el-table-column
					v-for="item in tableHeader"
					v-bind="item"
					:key="item.prop"
					header-align="center"
					align="center"
				>
					<template #header v-if="item.slotKey?.includes('tableHeaderSearch')">
						<el-input
							v-model.trim="search"
							size="small"
							:placeholder="getSearchInfo.label"
						/>
					</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)">

									<el-link type="danger" :underline="false">删除</el-link>
								</template>
							</el-popconfirm>
						</template>
					</template>
				</el-table-column>
			</el-table>

			<!-- 分页区域-->
			<el-pagination

				@current-change="handleCurrentChange"
			></el-pagination>
		</div>
	</div>
</template>

<script setup lang="ts">

// 搜索过滤
const filterTableData = computed(() =>
	props.tableData?.filter(
		(data) =>
			!search.value ||
			String(data[getSearchInfo.value.prop])
				.toLowerCase()
				.includes(search.value.toLowerCase())
	)
);
// 计算那列用于展示搜索
const getSearchInfo = computed(() => {
	let searchInfo = { label: '', prop: '' };
	props.tableHeader?.find((v) => {
		if (v.searchFields) {
			searchInfo = { label: v.label, prop: v.prop };
			return true;
		}
	});
	return searchInfo;
});

// 序号根据数据长度计算
const orderHandler = (index: number) => {
	const { pageNum, pageSize } = props;
	// 第0条 * 每页条数 + 当前索引+1

};

//  页数改变

				if (idsArr?.includes(row.id.toString())) {
					//重要
					nextTick(() => multipleTableRef.value?.toggleRowSelection(row, true));
				}
			});
		} else {
			multipleTableRef.value!.clearSelection();
		}
	}
};

const selectableCallback = (row: any) => {
	const idsArr = props.selectionIds?.split(',');
	if (props.isDisableSelection && idsArr?.includes(row.id.toString())) {
		return false;
	}
	return true;
};
watch(
	() => props.tableData,
	(newV) => {

			// console.log('🤺🤺  selectionIds🚀 ==>:', props.selectionIds);
			// console.log('🤺🤺  newV ==>:', newV);
			toggleSelection(toRaw(newV));

	}
);

// 搜索区域高度及默认值
const Height = ref();
// 减去搜索区域高度后的table，不能有默认值不然会出现滚动条
const excludeSearchAreaAfterTableHeight = ref();

// 获取表格高度-动态计算搜索框高度（onMounted、resize，208是已知的面包屑tebView高度）
const updateHeight = () => {
	let wrapEl = document.querySelector('.scrollbar-height') as HTMLElement | null;

	Height.value = wrapEl.getBoundingClientRect().height;
	// console.log('🤺🤺  🚀 ==>:', wrapEl.getBoundingClientRect());
	if (props.isShowSearchRegion) {

onMounted(() => {

});

window.addEventListener('resize', updateHeight);
defineExpose({

</script>

<style scoped lang="scss">
.container {

			margin-top: 20px;
		}
	}
}
// 穿透父组件
:deep(.el-link) {
	padding-left: 10px;
}
</style>

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
							v-for="option in item.selectOptions"
							:key="option.value"
							:label="option.label"
							:value="option.value"
						>
							<zw-tooltip-omit :content="option.label"></zw-tooltip-omit>
						</el-option>
					</el-select>

					<el-cascader
						v-if="item.type === FormOptionsType.CASCADER"
						v-model.lazy="searchForm[item.vm]"
						:options="item.cascaderOptions"
						v-bind="item.props"
						class="ml10 w100"
					/>

					<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')">
						<SvgIcon name="ant-ReloadOutlined"></SvgIcon>
						重置
					</el-button>
					<el-button type="primary" @click="onSearch()">
						<SvgIcon name="ant-SearchOutlined"></SvgIcon>
						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">
					<el-form-item>
