unity 通过 二维数组序列化 实现二维数组在编辑器面板查看和配置数据

实现思路如下：

1、定义一个二维数组数据类

2、奖数据类标记为 Serializable  并实现 unity内置的  ISerializationCallbackReceiver接口，接口提供了序列化和反序列化方法，参见官方文档（文档中给出了字典的序列化方法）：Unity - Scripting API: ISerializationCallbackReceiver

3、使用unity序列化系统可识别的数据存储二维数组中的数据，这里使用一维数组

4、将数据类作为变量，重写主体类的inspector编辑器面板，并提供数据操作方法

代码如下：

数据类

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
[System.Serializable]
public class DataGrid2 : ISerializationCallbackReceiver

    #region 数据类内容
    /// <summary>

    [HideInInspector] public List<string> columnNames = new List<string>();

    [SerializeField] public string[,] data = new string[0, 0];
