Gudermannian Function

I want to evaluate numerically  the Gudermannian fonction over a range 
of values but without  any success so far:

Table[{x, Gd [x]}, {x, 0, 1, 0.1}]
will return me Gd[0],  Gd[0.1] .. and so on

As  Gd may be an unknown  function, I try what seems to me,  a newcomer 
to Mathematica 5 - an  equivalent mathematical expression:

Table[{x,  2 ArcTan Exp [x] - Pi/2}, {x, 0,  1,  0.1}]

but then only Exp[x] is numerically evaluated .

Thanks for any help
