Thanks, I was doing that, but without reading through every option
of every function, they all seem to do something more
complicated, like merge or joinby,
append_fields doesn't look very convenient, adds one by one
looking some more recursive_fill_fields seems also to do the
loop (but also handles nested structured arrays)
tt = np.empty((10,1),dt2)
So, I guess the answer is, loop over columns of structured arrays
