oops, another error. The example should be: Table(f,[1,2,1],[2,6,2]) returns [[f(1,2),f(1,4),f(1,6)],[f(2,2),f(2,4),f(2,6)]]

(Disclaimer: Mathematica is a trademark of Wolfram Research Inc, who is not affliated with this project) What you suggested is a function called Outer in Mathematica. The Table function is in a sense multi-dimentional version of Range, so they share syntax form.
