使用react js合并和显示表中的对象数据数组

import React, { Component } from 'react';

class Table extends Component {
  constructor(props) {
    super(props);
    this.state = {
      data: [
        { id: 1, name: 'John', age: 25 },
        { id: 2, name: 'Jane', age: 30 },
        { id: 3, name: 'Bob', age: 35 }
      ]
    };
  }

  mergeData = () => {
    // 合并数据的逻辑
    // 示例：将name和age字段合并为一个字符串
    const mergedData = this.state.data.map(item => ({
      ...item,
      mergedField: `${item.name} (${item.age})`
    }));

    this.setState({ data: mergedData });
  };

  render() {
    return (
      <div>
        <button onClick={this.mergeData}>合并数据</button>
        <table>
          <thead>
            <tr>
              <th>ID</th>
              <th>Name</th>
              <th>Age</th>
              <th>Merged Field</th>
            </tr>
          </thead>
          <tbody>
            {this.state.data.map(item => (
              <tr key={item.id}>
                <td>{item.id}</td>
                <td>{item.name}</td>
                <td>{item.age}</td>
                <td>{item.mergedField}</td>
              </tr>
            ))}
          </tbody>
        </table>
      </div>
    );
  }
}

export default Table;
