Hi Jason,
Glad we could help, and that your problem seemed to get worked out.
I agree that VLArrayCol would be nice, even though I still think that nested
tables handle this (albeit with a little more syntax). Feel free to open an
issue on github about this, including some of the comments and re

I found this question that is trying to do exactly what I want to do:

Also note that whenever you are dealing with variable length stuctures,

Hi Jason,
You can try nesting variable length arrays inside of your table (
http://www.pytables.org/docs/manual/ch04.html#VLArrayClassDescr). You might
need to refer to nested tables to get an idea of how to do this (
http://www.pytables.org/docs/manual/ch03.html#id332794). On the HDF5 level,

Hi,
I've been attempting to use pyTables to store data from a
data acquisition system that I'm using for my experimental work. I currently
make use of several pytables tables to store the data and really like the
querying ability that the table object provides. But I have an issue with
