Used masked table instead of object columns? #114

Open taldcroft opened 6 years ago

taldcroft commented 6 years ago

Currently if one explicitly sets continuity so that auto-fetching of continuity is disabled, then the output columns are all Object type. Instead this could return MaskedColumns with the missing values masked. Maybe this is only low priority since this mode of operation is atypical.

In [33]: states.get_states('2017:300', '2017:302', state_keys=['q1', 'fep_count'], continuity={})
Out[33]:
<Table masked=False length=92>
