Maybe you don't need to. This recent enhancement allows you to use a dtype as a description: http://www.pytables.org/trac/browser/trunk/tables/file.py?rev=4230 633 `description` 634 This is an object that describes the table, i.e. how many 635 columns it has, their names, types, shapes, etc. It can be 636 any of the following: 650 A NumPy dtype 651 A completely general structured NumPy dtype is accepted 652 too, and its field structure will be reflected in the 653 new `Table` object. Bonus tip: The easiest way I've found to turn a dtype into something which is easier to modify (combine, prune, ...), is eval(str(x.dtype)) which returns a list of tuples. ndarray.view() and friends are a bit picky and won't accept, say, a list of lists.
