In this work, we attempted to combine the Pad$\\rm \\acute{e}$ approximations with the latest Pantheon+ sample for testing cosmological principle. Based on the Pad$\\rm \\acute{e}$ approximations, we first gave the cosmographic constraints on the different order polynomials including third-order (Pad$\\rm \\acute{e}$$_{(2,1)}$), fourth-order (Pad$\\rm \\acute{e}$$_{(2,2)}$) and fifth-order (Pad$\\rm \\acute{e}$$_{(3,2)}$).
