In a similar situation, I was able to do it as follows:

,----
| #+srcname: org2cw
| #+begin_src python :results output :exports none
|   s = ""
|   for row in table:
|       ...do something with row and modify s...
|   print s
| 
| #+end_src
| 
| #+call: org2cw(table=support.obs) :file support.obs.cwiki
| 
| #+call: org2cw(table=support) :file support.cwiki
| 
`----

Each #+call is given a different table as an argument:

,----
| #+tblname: support.obs
| <table elided>
| 
| #+tblname: support
| <table elided>
`----

Note the role of ``table'' as the parameter name in the #+call:s
and its use as a variable in the source block.

HTH,
Nick
