Well, no and yes. No because there is not a high level method to do
that. Yes because you can do this manipulating somewhat the objects.

Look at the attachment, were I wrote a simple example of doing that.
The output looks like:

$ python add-column.py
Contents of the original table: NestedRecArray[
('Particle:     10', 10, 0, 100.0, 100.0),
('Particle:     11', 11, -1, 121.0, 121.0),
('Particle:     12', 12, -2, 144.0, 144.0)
]
Contents of the table with column added: NestedRecArray[
('Particle:     10', 10, 0, 100.0, 100.0, 0),
('Particle:     11', 11, -1, 121.0, 121.0, 0),
('Particle:     12', 12, -2, 144.0, 144.0, 1)
]

In the future, it would be interesting to create a high level method
to easy such operation.
