在React中创建一个能改变行数和列数的网格系统？

import React, { Component } from 'react';

class GridSystem extends Component {
  constructor(props) {
    super(props);
    this.state = {
      rowCount: 3,
      columnCount: 3
    };
  }

  handleChangeRowCount = (event) => {
    this.setState({ rowCount: parseInt(event.target.value) });
  }

  handleChangeColumnCount = (event) => {
    this.setState({ columnCount: parseInt(event.target.value) });
  }

  render() {
    const { rowCount, columnCount } = this.state;

    // 创建网格系统的行和列
    const rows = [];
    for (let i = 0; i < rowCount; i++) {
      const columns = [];
      for (let j = 0; j < columnCount; j++) {
        columns.push(<div key={j} className="column"></div>);
      }
      rows.push(<div key={i} className="row">{columns}</div>);
    }

    return (
      <div>
        <div>
          <label>行数:</label>
          <input type="number" value={rowCount} onChange={this.handleChangeRowCount} />
        </div>
        <div>
          <label>列数:</label>
          <input type="number" value={columnCount} onChange={this.handleChangeColumnCount} />
        </div>
        <div className="grid-system">
          {rows}
        </div>
      </div>
    );
  }
}

export default GridSystem;
