Thanks for your support!
Support for NumPy dtypes in createTable has been implemented quite a while ago and, if fact, your script works perfectly here. Which version of PyTables are you using? Please update to a more recent version and try again. Cheers, -- Francesc Alted ------------------------------------------------------------------------------ Beautiful is writing same markup.
