怎么用C#中的交错数组编写一个九九乘法表？请求帮助菜鸟：（下面是我自己写的，

int[][] number = new int[9][];
for (int i = 0; i < 9; i++)
{
for (int j = 0; j < i; j++)
{
number[i][j] = (i + 1) * (j + 1);
Console.Write(number[i][j] + " ");
}
Console.WriteLine();
}

 using System;

public class Test
{
    public static void Main()
    {
        // your code goes here
        int[][] number = new int[9][];
        for (int i = 0; i < 9; i++)
        {
            number[i] = new int[i + 1];
            for (int j = 0; j <= i; j++)
            {
                number[i][j] = (i + 1) * (j + 1);
                Console.Write(number[i][j] + " ");
            }
            Console.WriteLine();
        }
    }
}
