Yes, you can filter a 2D array based on conditions for rows and columns using logical operators.

arr_2d = np.array([[1, 2, 3],
                   [4, 5, 6],
                   [7, 8, 9]])

row_condition = arr_2d[:, 1] > 2
col_condition = arr_2d[0, :] % 2 == 0

filtered_arr_2d = arr_2d[row_condition][:, col_condition]
print(filtered_arr_2d)
# Output:
# [[2]
#  [8]]
