推荐答案

if You mean Table such as two Dimensional Array in C# so one of ways :

// Table num1
          int[,] num1 = {
                            {1,2},
                            {3,4},
                            {5,6},
                            {7,8}
                        };
          // Table num2
          int[,] num2 = {
                            {9,10},
                            {11,12},
                            {13,14},
                            {15,16}
                         };
          // Table num3, num4
          int[,] num3 = new int[4, 2];
          int[,] num4 = new int[4, 2];

          // Save to Table num3
          for (int i = 0; i < 4; i++)
              for (int j = 0; j < 2; j++)

                  num3[i, j] = num1[i, j];

          // Save to Table num4
          for (int i = 0; i < 4; i++)
              for (int j = 0; j < 2; j++)
                  num4[i, j] = num2[i, j];
