One nice way to get around headers is through indexing into variable
references, so for example the following two are equivalent...

#+results: my-table
|       Date |   Kg |
|------------+------|
| 2010-02-21 | 95.0 |
| 2010-02-22 | 93.0 |
| 2010-02-23 | 92.0 |
| 2010-02-24 | 91.5 |
| 2010-02-25 | 91.0 |
| 2010-02-26 | 92.0 |

#+begin_src python :var data=my-table[2:-1] :results output
  print str(data)
#+end_src

#+results: my-table-nohdr
| 2010-02-21 | 95.0 |
| 2010-02-22 | 93.0 |
| 2010-02-23 | 92.0 |
| 2010-02-24 | 91.5 |
| 2010-02-25 | 91.0 |
| 2010-02-26 | 92.0 |

#+begin_src python :var data=my-table-nohdr :results output
  print str(data)
#+end_src
