所有的渲染相关的操作,都写在 columns里面 render中
render: (value, row, index) =>({
children: value, // 页面显示的组建,如<a></a> ,input
props: {}, // 行列合并在这里的 cloSpan和 rowSpan
}),

官网table行列合并
实际案例
const mergeCells = (text, array, columns) => {
const temp = {}; // 当前重复的值,支持多列
let i = 0;
if (text !== temp[columns]) {
temp[columns] = text;
array.forEach((item) => {
if (item[columns] === temp[columns]) {
i += 1;
}
});
}
return i;
};
rowSpan
就是渲染的行数,默认为1,设置0则不渲染,案例中 商品ID为222 的rowSpan
是3
// dataSource表格数据
const dataSource = [
{ key: 1, goodsId: 222,seckillId: '123' },
{key: 2, goodsId: 222, seckillId: 'ddaf'},
{key: 3, goodsId: 222, seckillId: 'ddaf'},
{key: 4, goodsId: 3, seckillId: 'ddaf'},
{key: 5, goodsId: 252, seckillId: 'ddaf'},
{key: 6, goodsId: 33, seckillId: 'ddaf'},
{key: 7, goodsId: 33, seckillId: 'ddaf'},
{key: 8, goodsId: 5, seckillId: 'ddaf'},
]
const columns = [
{
title: '秒杀ID',
dataIndex: 'seckillId',
key: 'seckillId',
},
{
title: '商品ID',
dataIndex: 'goodsId',
key: 'goodsId',
render: (text, record, index) => {
const obj = {
children: text,
props: {},
};
// 如果上面有相同的数据,如商品ID 222, 则rowSpan = 0
if ((index > 0 && text !== dataSource[index - 1].goodsId) || index == 0) {
obj.props.rowSpan = mergeCells(record.goodsId, dataSource, 'goodsId')
} else {
obj.props.rowSpan = 0;
}
return obj;
},
}]
<Table
bordered
pagination={pagination}
locale={{ emptyText: '暂无数据' }}
dataSource={dataSource}
columns={columns.map(v => Object.assign({}, v, { align: 'center' }))}
size='middle'
