Is there any Local Report expression to calculate the total of cells in the same rows or columns?

I hope there is such an expression to make my work simpler, easier, like this:

For total of cells in the same rows:

Total    |     Column 1    |    Column 2    |    Column 3
 10               1                5                 4            //1 + 5 + 4 = 10
 20              10                8                 2            //10 + 8 + 2 = 20
...

Or for total of cells in the same columns:

               Column 1    |    Column 2    |    Column 3
Total            16                9                 13
Row 1            1                 4                 5
Row 2            8                 3                 2
Row 3            7                 2                 6

Your help would be highly appreciated! If you know only one of two, please feel free to give an answer. Thank you very much in advance!
