        static void Main(string[] args)
        {
            const int ROWS=3;
            const int COLS=3;
            int[,] arr=new int[ROWS,COLS] {
                {0,1,2},
                {3,4,5},
                {6,7,8}
            };

            for (int i = 0,r=0; i < (ROWS*2 + 1); ++i)
            {
                if (i == 0)
                {
                    Console.Write("┌");
                    for (int j = 0; j < COLS; ++j)
                    {
                        if(j<COLS-1)
         正闹迅                   Console.Write("─┬");
                        else
     弯此                       Console.Write("─┐");
                    }
                }
                else if (i == ROWS*2)
                {
                    Console.Write("└");

                    for (int j = 0; j < COLS; ++j)
                    {
                        if (j < COLS - 1)
                            Console.Write("─┴");
                        else
                            Console.Write("─┘");
                    }
                }
                else if (i % 2 == 0)
                {
                    Console.Write("├");
                    for (int j = 0; j < COLS; ++j)
                    {
                        if (j < COLS - 1)
                            Console.Write("─┼");
          举此              else
                            Console.Write("─┤");
                    }
                }
                else
                {
                    Console.Write("│");
                    for (int j = 0; j < COLS; ++j)
                    {                        
                        Console.Write(" {0}│",arr[r, j]); 
                    }
                    ++r;
                }
