pointer to code memory

hello every one

i am trying to create a pointer to two dimensional character array located in code space of 8051

i am getting a warning of c182:pointer to different objects

my code is like this

unsigned char code table[120][5]={some values}//array daclaration

unsigned char code **ptr;//pointer to code memory

ptr = table;//trying to access this way

can any one tell what is the mistake in it

thanks®ards
