Request: write table with fixed width AND commented header #5922

I want to write some data to an output file using astropy's ascii module for writing tables.

I want fixed width columns and a commented header using the # character. As far as I can see, I can either write using a fixed column width:

from astropy.io import ascii
from astropy.table import Table
out_data = [('name1', 'name2'), (20., .7)]
data = Table(out_data, names=('names', 'some_data'))
ascii.write(data, 'test.dat', format='fixed_width', delimiter=None)

which produces

 names  some_data 
  name1       20.0 
  name2        0.7 

or a commented header using

ascii.write(data, 'test.dat', format='commented_header', delimiter=None)

which results in

# names some_data
name1 20.0
name2 0.7

What I want is

# names  some_data 
  name1       20.0 
  name2        0.7 

I have not been able to combine these two outputs as shown. I could modify the name of my first table element to # names, but that feels a bit hackish. Is this the proper way to do this?
