A Learning TableForm Problem

I need to know why this isn't working for me.  The example I am given is:
Find an estimate for the zero of the Polynomial.  f(x)=x^3-4x^2-2x+8

On a graph the estimated zero is between (1,2)   and it asks us to divide
the interval into tenths

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

The > is as close as I can get to a right arrow sign

The example I have shows a table  with 2 columns and appropriate numbers,
but I cannot get this to display on Mathematica for me.  Any ideas?

Thanks
Carlos
