七、📝 结语

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-tableref="multipleTableRef"v-bind="$attrs"stripestyle="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-columntype="selection"width="30"v-if="isSelection":reserve-selection="true":selectable="selectableCallback"/><el-table-columntype="index"label="序号"min-width="60":index="orderHandler"align="center"/><el-table-columnv-for="item in tableHeader"v-bind="item":key="item.prop"header-align="center"align="center"><template #header v-if="item.slotKey?.includes('tableHeaderSearch')"><el-inputv-model.trim="search"size="small":placeholder="getSearchInfo.label"/></template><template #default="{ row }" v-if="item.slotKey"><slotv-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--><el-paginationv-if="paginationFlag"background:page-sizes="pageSizesArr":current-page="pageNum":page-size="pageSize":layout="layout":total="total"popper-class="pagination-popper"@size-change="handleSizeChange"@current-change="handleCurrentChange"></el-pagination></div></div>
</template><script setup lang="ts">
import { onMounted, ref, watch, toRaw, nextTick, computed } from 'vue';
import { ElTable } from 'element-plus';
const multipleTableRef = ref<InstanceType<typeof ElTable>>();import myEmits from './newTableConfig/emits';
import myProps from './newTableConfig/props';
const emits = defineEmits(myEmits);
const props = defineProps(myProps);
const search = ref('');// 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+1return (pageNum - 1) * pageSize + index + 1;
};//  页数改变
const handleSizeChange = (val: number | string) => emits('handleSizeChange', val);
// 当前页改变
const handleCurrentChange = (val: number | string) => emits('handleCurrentChange', val);// 编辑、删除
const handleEdit = (row: object) => emits('handleEdit', row);
const handleDelete = (id: number) => emits('handleDelete', id);
// 复选框
const onSelectionChange = (val: any) => emits('selection-table-change', val);//记录每行的key值
const getRowKeys = (row: any) => row.id;// 根据父组件传递的id字符串，默认选中对应行
const toggleSelection = (rows?: any) => {if (props.isSelection) {if (rows) {rows.forEach((row: any) => {const idsArr = props.selectionIds?.split(',');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) => {if (!!props.selectionIds) {// 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;if (!wrapEl) return;Height.value = wrapEl.getBoundingClientRect().height;// console.log('🤺🤺  🚀 ==>:', wrapEl.getBoundingClientRect());if (props.isShowSearchRegion) {excludeSearchAreaAfterTableHeight.value = `calc(100vh - ${200 + Height.value}px)`;}
};onMounted(() => {// 表格下拉动画const tableContainer = <HTMLElement>document.querySelector('.container');setTimeout(() => {if (tableContainer) tableContainer.style.transform = 'translateY(0)';updateHeight();}, 800);

defineExpose({toggleSelection,

</script><style scoped lang="scss">

}
// 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-inputv-if="item.type === FormOptionsType.INPUT"v-model.lazy.trim="searchForm[item.vm]"v-bind="item.props"class="ml10 w100"></el-input><el-selectv-if="item.type === FormOptionsType.SELECT"v-model.lazy="searchForm[item.vm]"v-bind="item.props"class="ml10 w100"fit-input-width><el-optionv-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-cascaderv-if="item.type === FormOptionsType.CASCADER"v-model.lazy="searchForm[item.vm]":options="item.cascaderOptions"v-bind="item.props"class="ml10 w100"/><el-date-pickerv-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
