Bryan Cutler commented on ARROW-1614:
-------------------------------------
bq. As this is for the case where all tensors in the array are of the same
shape I propose we store the data in a single Tensor. Is there a good reason
not to do that?
I believe if there is a single pyarrow.Tensor serialized in the backing binary
array, that array will have a length of 1. Then if placing in a Table or
RecordBatch, would restrict it to 1 row for the other columns as well.

> In an Arrow table, we would like to add support for a column that has values
