如何将1d转换为2d并将其存储在react原生状态中？

import React, { Component } from "react";

class MyComponent extends Component {
  constructor(props) {
    super(props);
    // 定义一维数组
    const oneDimensionalArray = [1, 2, 3, 4, 5, 6, 7, 8, 9];
    // 定义二维数组
    const twoDimensionalArray = [];

    // 将一维数组转换为二维数组
    const rows = 3; // 行数
    const columns = 3; // 列数
    for (let i = 0; i < rows; i++) {
      twoDimensionalArray[i] = [];
      for (let j = 0; j < columns; j++) {
        const index = i * columns + j;
        twoDimensionalArray[i][j] = oneDimensionalArray[index];
      }
    }

    this.state = {
      twoDimensionalArray: twoDimensionalArray
    };
  }

  render() {
    const { twoDimensionalArray } = this.state;

    return (
      <div>
        {/* 在页面上展示转换后的二维数组 */}
        {twoDimensionalArray.map((row, rowIndex) => (
          <div key={rowIndex}>
            {row.map((value, columnIndex) => (
              <span key={columnIndex}>{value} </span>
            ))}
          </div>
        ))}
      </div>
    );
  }
}

export default MyComponent;
