Let \((W,S)\) be a Weyl group with generating set \(S\). The concept of the character table of a generic Iwahori-Hecke algebra \(H(W)\) of \(W\) was introduced by M. Geck and G. Pfeiffer [in Adv. Math. 102, No. 1, 79-94 (1993; Zbl 0816.20034)] as a square matrix which maps under specialization to the character table of the corresponding Weyl group \(W\). In this paper the author determines the character table for the Iwahori-Hecke algebra \(H(W)\) for \(W=B_n\). Some concepts of type \(A_n\) are generalized such as the Murnaghan-Nakayama formula and the Littlewood-Richardson rule. Computer programs such as GAP and CHEVIE are used in the calculation.
