This is not a trivial calculation. The following is excerpted from a Wikipedia article on Sudoku.
The number of classic 9×9 Sudoku solution grids was shown in 2005 by Bertram Felgenhauer and Frazer Jarvis to be 6,670,903,752,021,072,936,960. The number of essentially different solutions, when symmetries such as rotation, reflection and relabelling are taken into account, was shown by Ed Russell and Frazer Jarvis to be just 5,472,730,538.

look across and see if there is the number 1 anywhere in the row, or in the box, or in the coulumn- if the answer is no to all put a small one in the box-then do the same for number 2-9.

i think itz 9! or 9*8*7*6*5*4*3*2*1=362880 (for one row) i guess for the table it would be 362880! - [8!+7!+6!+5!+4!+3!+2!] = 316648
