We explore theoretically the novel superfluidity of harmonically-trapped polarized ultracold fermionic atoms in a two- dimensional optical lattice by solving the Bogoliubov-de Gennes equations. The pairing amplitude is found to oscillate along the radial direction at low particle density and along the angular direction at high density. The former is consistent with the existing experiments and the latter is a newly predicted Fulde-Ferrell-Larkin-Ovchinnikov state, which can be tested in experiments.
