writing a basic ascii table from QTable is broken

from astropy.table import QTable,Column
import astropy.units as u
q = QTable()
q['dt'] = [1,2,3]*u.s
q.write('foo.txt',format='ascii.no_header',delimiter=',',formats={'dt':'%.18f'})

The write call throws an exception with “Quantity object has no name member”

If I look in _set_col_formats in io/ascii/core.py it says

if col.info.name in self.formats:
   col.info.format = self.formats[col.name]

That second line probably should say “col.info.name” instead. A similar change would need to be made in the fast writer

EDIT: Syntax highlighting

I can also probably make a quick fix if @mcbeth does not have time.

Yes, that exact code worked on 1.2.4
