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 Sigismond K.
