在Vue3中使用and design设置表格序号自增时，设置列的customRender属性为: ({ index }: { index: number }) =>${index + 1}；如果有分页，设置全部页面自增：customRender: ({ index }: { index: number }) => {
return${(pagination.current - 1) * pagination.pageSize + index + 1}
}
不要忘记设置pagination 的chage事件，在change事件中要更新当前页面索引current，才能生效。
<a-tablesize="small"bordered:pagination="pagination":columns="columns":dataSource="state.ds":rowKey="(record: any) => record.id":loading="state.loading">
const pagination = reactive({current: 1,pageSize: 15,showTotal: (total: number) => `共${total}条记录`,onChange: (page: number) => {pagination.current = page}})const columns = [{title: '序号',align: 'center',// customRender: ({ index }: { index: number }) => `${index + 1}` //每页自增customRender: ({index }: {index: number }) => {return `${(pagination.current - 1) * pagination.pageSize + index + 1}`}},{title: '年份', dataIndex: 'pickYear', align: 'center' },]
