Issue Printing Tables in Jupyter Notebook

I've been trying to display some tables in sage, in particular I would like to display tables that contain matrices as nice output in a jupyter notebook.

I seem to not be able to get table to work at all. In particular, if I open a new notebook and run the chunk

%display latex
blah = [('A', 'B', 'C'), (0, 1, 2), (3, 4, 5), (6, 7, 8)]

It returns


which appears to be some sort of hash value? I can't find anything on this to help debug.

For reference, I'm still running sage 8.4. The environments on the system I'm working on are a little messed up, so I could update to the newest version if there is reason to believe that's the issue, but I would rather not if I can avoid it.

Are you running a Python 3 version of Sage? That is the only way I have been able to reproduce this problem. Note that the Python 3 version is still somewhat experimental.

Thanks for reporting! I confirm the same behaviour with SageMath 8.7. Fixing this is now tracked at

As a workaround, some alternative solutions are offered as answers to

To make the import statements work, install the corresponding extra packages:

sage --pip install pandas
sage --pip install tabletext
sage --pip install tabulate

Ah, thanks for the reference. Does this mean that the issue is entirely on the ipython side of things? These seem to be alternative methods for printing tables, but don't explain why I'm getting some hash value when I try to use the builtin table command.

That being said, I'm not really attached to the table command other than the convenience, so I'll dive into this thread and see if I can get something else to work.

That said, table has a long and distinguished history in Sage, so that should definitely be fixed in Jupyter.

@kcrisman - There is now a Sage Trac ticket for this problem, I edited my answer to make it clearer this is indeed a bug, and the "solutions" I first gave can be thought of as a workaround until this is fixed.

The "some hash value" is simply the base-64 encoding of the table. I know images are passed to the notebook in base64 encoding, and for some reason it's (incorrectly?) doing that with the table as well. You can see that by running import base64; print(base64.b64decode("""PGRpdiBjbG..."""))
