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.
