1. 功能概述

本教程将介绍如何使用 Vue 3 和 arco 组件库实现表格合并功能。具体来说，我们会根据表格数据中的某个字段（如 type）对表格的某一列（如入库类型列）进行合并，同时将质检说明列合并为一列。

2. 数据准备

首先，我们需要准备一份数据示例：

import { ref, computed } from 'vue';const storageGoodsVosdata = ref([{id: 1,workOrderId: 'WO001',goodsNo: 'G001',goodsName: 'Test Product 1',skuCode: 'SKU001',skuInfo: 'Color: White; Style: Simple',quantity: 1,type: 0,typeName: 'Defective Incoming',reasonCode: 'R01',reasonCodeStr: 'Label/Certificate/Manual/Missing or Damaged',logisticReceiptsUrls: ['https://example.com/image1.jpg','https://example.com/image2.jpg',],outerPackagingUrls: ['https://example.com/image3.jpg','https://example.com/image4.jpg',],housekeepingDiagramUrls: ['https://example.com/image5.jpg','https://example.com/image6.jpg',],createTime: '2025-02-12 09:43:31',},{id: 2,workOrderId: 'WO001',goodsNo: 'G001',goodsName: 'Test Product 1',skuCode: 'SKU001',skuInfo: 'Color: White; Style: Simple',quantity: 1,type: 0,typeName: 'Defective Incoming',reasonCode: 'R01',reasonCodeStr: 'Label/Certificate/Manual/Missing or Damaged',logisticReceiptsUrls: ['https://example.com/image1.jpg','https://example.com/image2.jpg',],outerPackagingUrls: ['https://example.com/image3.jpg','https://example.com/image4.jpg',],housekeepingDiagramUrls: ['https://example.com/image5.jpg','https://example.com/image6.jpg',],createTime: '2025-02-12 09:43:31',},{id: 3,workOrderId: 'WO001',goodsNo: 'G002',goodsName: 'Test Product 2',skuCode: 'SKU002',skuInfo: 'Color: Black; Style: Modern',quantity: 1,type: 1,typeName: 'Goods Incoming',reasonCode: 'R01',reasonCodeStr: 'Label/Certificate/Manual/Missing or Damaged',logisticReceiptsUrls: ['https://example.com/image7.jpg','https://example.com/image8.jpg',],outerPackagingUrls: ['https://example.com/image9.jpg','https://example.com/image10.jpg',],housekeepingDiagramUrls: ['https://example.com/image11.jpg','https://example.com/image12.jpg',],createTime: '2025-02-12 09:43:31',},{id: 4,workOrderId: 'WO001',goodsNo: 'G002',goodsName: 'Test Product 2',skuCode: 'SKU002',skuInfo: 'Color: Black; Style: Modern',quantity: 1,type: 1,typeName: 'Goods Incoming',reasonCode: 'R01',reasonCodeStr: 'Label/Certificate/Manual/Missing or Damaged',logisticReceiptsUrls: ['https://example.com/image7.jpg','https://example.com/image8.jpg',],outerPackagingUrls: ['https://example.com/image9.jpg','https://example.com/image10.jpg',],housekeepingDiagramUrls: ['https://example.com/image11.jpg','https://example.com/image12.jpg',],createTime: '2025-02-12 09:43:31',},
]);const sortedStorageData = computed(() => {return [...storageGoodsVosdata.value].sort((a, b) => a.type - b.type);
});

3. 表格合并方法

接下来，我们定义一个 spanMethod 函数来处理表格合并逻辑：

function spanMethod({ rowIndex, columnIndex }) {if (columnIndex === 0) { // 只处理第一列（入库类型列）const arr = sortedStorageData.value;const item = arr[rowIndex];// 如果是第一行，或者当前行的类型与前一行不同if (rowIndex === 0 || arr[rowIndex - 1].type !== item.type) {// 计算当前类型的连续行数const count = arr.slice(rowIndex).findIndex(row => row.type !== item.type);return {rowspan: count === -1 ? arr.length - rowIndex : count,colspan: 1,};}// 其他行不显示return {rowspan: 0,colspan: 0,};}// 处理质检说明列（最后一列）if (columnIndex === 8) { // 质检说明列的索引if (rowIndex === 0) {return {rowspan: sortedStorageData.value.length,colspan: 1,};}return {rowspan: 0,colspan: 0,};}
}

模板部分

最后，我们在模板中使用 a-table 组件来渲染表格，并绑定数据和合并方法：

<template><a-table:data="sortedStorageData":bordered="{ cell: true }":pagination="false":span-method="spanMethod"><template #columns><a-table-column title="Incoming Type" data-index="typeName" align="center" :min-width="180"><template #cell="{ record }">{{ record.type === 1 ?

</style>

5. 解释

数据排序：使用 computed 计算属性对数据进行排序，确保相同类型的数据相邻。
表格合并逻辑：spanMethod 函数根据列索引和行索引来决定哪些单元格需要合并。对于入库类型列，根据 type 字段合并相同类型的行；对于质检说明列，将所有行合并为一列。
模板渲染：使用 a-table 组件渲染表格，并通过 #columns 插槽定义表格列。每个列可以通过 #cell 插槽自定义单元格内容。

通过以上步骤，你就可以实现一个带有合并单元格功能的表格。
