I figured it how to create a new table with compression. I did not
know that I was supposed to look in the filters section. Since I did
not know what filters were, I did not know that had anything to do
with compression.
I still don't know how to compress an already created table.
Francesc, thanks so much for creating Pytables. Really appreciate it.
I am still playing with it and have not started using it for serious
work, but hope to do so soon.
