using an array as function parameter

Question

I tried to implement a function with the following prototype but I got an error during the compilation time.
void print_tab(int tab[][])

after I replaced the 'int tab[][]' with 'int tab[][N]' the error has gone, (N is a constant defined using #define). can someone explain me why?
