In [R. Clarke, G.N. Han, J. Zeng, A combinatorial interpretation of the Seidel generation of q-derangement numbers, Ann. Comb. 1 (1997) 313-327] Clarke, Han and Zeng introduced a generalized Euler's difference table. In this paper, we add a third variable and give a combinatorial interpretation of this generalization.
