  In this paper, we investigate the non-autonomous discrete
Kadomtsev-Petviashvili (KP) system in terms of generalized Cauchy matrix
approach. These equations include non-autonomous bilinear lattice KP equation,
non-autonomous lattice potential KP equation, non-autonomous lattice potential
modified KP equation, non-autonomous asymmetric lattice potential modified KP
equation, non-autonomous lattice Schwarzian KP equation and non-autonomous
lattice KP-type Nijhoff-Quispel-Capel equation. By introducing point
transformations, all the equations are described as simplified forms, where the
lattice parameters are absorbed. Several kinds of solutions more than
multi-soliton solutions to these equations are derived by solving determining
equation set. Lax representations for these equations are also discussed.
