You need a slight modification to your Table[] statement.  Try the following

	tbl = Table[{x, y, f[x, y]}, {x, 0, 3, 1}, {y, 0, 4, 2}];
	TableForm[Partition[Flatten[tbl], 3], 
	  TableHeadings -> {None, {"x", "y", "f[x, y]"}}, 
	  TableAlignments -> Center]

The key function here is TableForm[].

Regards,

Dave.
