Research direction

Start with the table API used by pick_files(), drop_files(), update(), and split_id in the issue example. Define the move operation around those existing behaviors, including the stated matching-column requirement, and verify that the listed files end up in the destination table and are removed from the source.

Description

documentation enhancement

Let's say you would like to move a list of files from an existing train table to an existing test table.
The easiest solution I found so far would be:

db['tmp'] = db['train'].pick_files(files)
db['tmp'].split_id = db['test'].split_id
db['train'].drop_files(files, inplace=True)
db['test'].update(db['tmp'])
db.drop_tables('tmp')

so it might be easier to have something like:

db['test'].move_files(db['train'], files)

Of course it will only work if your columns match, but the same is true for update().
