Tabulate raises `ValueError` with `np.array` as cell values

Follow up to: https://github.com/pandas-dev/pandas/issues/59588

tabulate can handle lists [1, 2] as cell values but not numpy arrays np.array([1, 2]):

>>> print(tabulate([[[1, 2], 3]]))
------  -
[1, 2]  3
------  -
>>> print(tabulate([[np.array([1, 2]), 3]]))

ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()

I'd expect a similar behavior or at least something like:

----------------  -
np.array([1, 2])  3
----------------  -
