>>> import numpy as np

Create a 2x3 BIOM table:

>>> data = np.asarray([[0, 0, 1], [1, 3, 42]])
>>> table = Table(data, ['O1', 'O2'], ['S1', 'S2', 'S3'])

Get the ids along the observation axis:

>>> print(table.ids(axis='observation'))
['O1' 'O2']

Get the ids along the sample axis:

>>> print(table.ids())
['S1' 'S2' 'S3']
