Description

pa.Table.from_arrays doesn't validate that the length of arrays and names matches. I think this should raise with a ValueError:

In [1]: import pyarrow as pa

In [2]: pa.Table.from_arrays([pa.array([1, 2]), pa.array([3, 4])], names=['a', 'b', 'c'])
Out[2]:
pyarrow.Table
a: int64
b: int64

In [3]: pa.__version__
Out[3]: '0.7.0'

(This is my first time using JIRA, hopefully I didn't mess up too badly)
