Is this a homework problem? I assume it is not.

I found no difficulty in displaying your table (perhaps you have some
punctuation problem):

Clear[f]; f[x_] := x^3 - 4*x^2 - 2*x + 8
TableForm[Table[{i, f[i]}, {i, 1, 2, 0.1}],
  TableHeadings -> {None, {"x", "f(x)"}}]

(I omit the output). It displays all right. I don't understand what you say
about the right arrow
