"data type not understood" error

[steven-murray]

Hi there,

I am trying to add a column to an existing table. The first column to be added gets added fine (the data added is just a np.arange() array).

However, when I try to add another column, I get told that the "data type not understood" on line 580 of basetable.py

No matter what I try I can't figure out how to get the type to be alright. The dtype of the data is 'float64' but the newdtype variable is showing (name, dtype('float64')). I'm not sure if the second element here should just be plain 'float64' and how to make it so if that is the case?

Cheers

Sorry for the delay - could you provide a short example that reproduces the issue? Thanks!
