[O] Question on formatting result blocks in LaTeX

[Richard Stanton]

Using Org-mode version 7.9.1 (release_7.9.1-163-g27101a @ 
c:/emacs/site-lisp/org-mode/lisp/), here's an example of some Python code with 
an output block:

#+name: read_excel
#+begin_src python :results output :exports both
from pandas import *
import requests, StringIO
xls = requests.get('http://www.econ.yale.edu/~shiller/data/chapt26.xls')
f = io.parsers.ExcelFile(StringIO.StringIO(xls.content))
dat=f.parse('Data',skiprows=[0,1,3,4,5,6,7],index_col=0).dropna(thresh=3).ix[:,'P':'CPI'].convert_objects()
print dat.head(5)
#+end_src

#+RESULTS: read_excel
: NOTE *** Ignoring non-worksheet data named u'PDVPlot' (type 0x02 = Chart)
: NOTE *** Ignoring non-worksheet data named u'ConsumptionPlot' (type 0x02 = 
Chart)
:          P     D     E     R  RLONG        CPI
: 1871  4.44  0.26  0.40  6.35   5.32  12.464061
: 1872  4.86  0.30  0.43  7.81   5.36  12.654392
: 1873  5.11  0.33  0.46  8.35   5.58  12.939807
: 1874  4.66  0.33  0.46  6.86   5.47  12.368896
: 1875  4.54  0.30  0.36  4.96   5.07  11.512651

When I export this org file to HTML, the output block has the same format 
(colors, etc.) as the source block. When I export to PDF via LaTeX,  however, 
the result block seems to get formatted as regular text, and looks nothing like 
the source block. Is there any way to get the same formatting for the result 
block as for the source block when exporting to LaTeX/PDF?

Thanks.
