With Mathematica version 6, you may now use the form

   Table[expr, {i, {i1, i2,...,ik}}]

in order to specify a particular list of values for the iterator i 
instead of a regularly incremented list.

For example:

   f[x_] := x^(-3) Cos[2 x]
   f1[x_] = f'[x]; f2[x_] = f''[x];

   info=Table[N@{x, f[x], f1[x], f2[x]}, {x, {-3, 1, 1/2, Pi, -5}}];
   headers = TraditionalForm /@

I would like to be able to input x-values and have the table display f(x), f'(x), and possibly f''(x) for a given function. I have already specified the function, and I have found the following input creates tables:
> Table[{x,f[x]},{x,-5,5,.5}]
> My problem is this: I would like to input specifc x-values, rather than use set intervals as defined in {x,-5,5,.5} above. Is there a way to specify a list of specific x values so that Mathematica computes the values of f[x] in table form?
