您想在每行中创建 2 个子行，但仅针对某些列。 您可以为此使用rowspan 。

您可以复制行（ row1-row1-row2-row2-row3-row3-... ），并将子行值放入其中（ row1_subrow1-row1_subrow2-row2_subrow1-row2_subrow2-... ），然后对列使用rowspan您想要展开（如图像中的部分和名称），展开奇数行并折叠此列的偶数行。

import React from "react";
import ReactDOM from "react-dom";
import "antd/dist/antd.css";
import "./index.css";
import { Table } from "antd";

let multiRowRender = (value, row, index) => {
  const obj = {
    children: value,
    props: {}
  };
  if (index % 2 === 0) {
    obj.props.rowSpan = 2;
  }
  if (index % 2 === 1) {
    obj.props.rowSpan = 0;
  }
  return obj;
};

const columns = [
  {
    title: "Number",
    dataIndex: "number"
  },
  {
    title: "Issue",
    dataIndex: "issue"
  },
  {
    title: "Name",
    dataIndex: "name",
    render: multiRowRender
  },
  {
    title: "Section",
    dataIndex: "section",
    render: multiRowRender
  }
];

let data = [
  {
    key: "1",
    name: "John Brown",
    issues: [32, 100],
    numbers: [18889898989, 545054],
    section: "sec 1"
  },
  {
    key: "2",
    name: "Jim Green",
    issues: [42, 50],
    numbers: [18889898888, 1420054],
    section: "sec 2"
  }
];
let data2 = [];
data.forEach(d => {
  data2.push({ ...d, issue: d.issues[0], number: d.numbers[0] });
  data2.push({
    ...d,
    issue: d.issues[1],
    number: d.numbers[1],
    key: d.key + "-row2"
  });
});
data = data2;

ReactDOM.render(
  <Table columns={columns} dataSource={data} bordered />,
  document.getElementById("container")
);
