antdesignvue表格行合并

Ant Design Vue 表格组件提供了 `spanMethod` 属性来实现单元格合并,你可以在该属性中指定一个回调函数来返回当前单元格是否需要合并,以及合并的行数和列数。
下面是一个示例代码:
```html
<template>
<a-table :columns="columns" :data-source="data" :row-key="record => record.key" :scroll="{ x: 'max-content' }">
<template #name="{ text, record, index }">
<span v-if="index === 0 || record.name !== data[index - 1].name">{{ text }}</span>
</template>
<template #age="{ text, record, index }">
<span v-if="index === 0 || record.name !== data[index - 1].name" :rowspan="getSpan('name', record.name)">{{ text }}</span>
</template>
<template #address="{ text, record, index }">
<span v-if="index === 0 || record.name !== data[index - 1].name" :rowspan="getSpan('name', record.name)" :colspan="getSpan('address', record.address)">{{ text }}</span>
</template>
</a-table>
</template>
<script>
export default {
data() {
return {
data: [
{ key: '1', name: 'John Brown', age: 32, address: 'New York No. 1 Lake Park' },
{ key: '2', name: 'Jim Green', age: 40, address: 'London No. 1 Lake Park' },
{ key: '3', name: 'Joe Black', age: 32, address: 'Sidney No. 1 Lake Park' },
{ key: '4', name: 'John Brown', age: 32, address: 'New York No. 2 Lake Park' },
{ key: '5', name: 'Jim Green', age: 40, address: 'London No. 2 Lake Park' },
{ key: '6', name: 'Joe Black', age: 32, address: 'Sidney No. 2 Lake Park' },
],
columns: [
{
title: 'Name',
dataIndex: 'name',
key: 'name',
slots: { customRender: 'name' },
},
{
title: 'Age',
dataIndex: 'age',
key: 'age',
slots: { customRender: 'age' },
},
{
title: 'Address',
dataIndex: 'address',
key: 'address',
slots: { customRender: 'address' },
},
],
nameSpanMap: {},
addressSpanMap: {},
};
},
methods: {
getSpan(columnKey, text) {
const spanMap = columnKey === 'name' ? this.nameSpanMap : this.addressSpanMap;
if (!spanMap[text]) {
spanMap[text] = 1;
return 1;
}
const span = spanMap[text];
spanMap[text] = span + 1;
return 0;
},
},
};
</script>
```
在上面的代码中,我们通过 `template` 标签指定了每一列的渲染方式,同时在 `spanMethod` 属性中指定了回调函数 `getSpan`。在该函数中,我们通过维护一个以列名和单元格文本为键的 Map 来计算每一个单元格需要合并的行数和列数,并返回给表格组件。最终,我们通过 `rowspan` 和 `colspan` 属性来指定合并的行数和列数。
