The help pages for *Grid* and *Item* contain numerous and well
illustrated examples of such things. With the data set you provided, one
way of highlighting the primes, among many others, could be as follows,
myData = {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}};
Grid[myData /. p_ /; PrimeQ[p] -> Item[p, Background -> Orange],
Frame -> True, FrameStyle -> Directive[Orange, Thickness[2]]]
