Hi Jay,

This sounds like a question about the new exporter which is beyond my
ken.

However, code blocks may be called from Org-mode tables, using the `sbe'
[1] macro.

Hope this helps,

Footnotes: 
[1]  
,----[sbe]
| sbe is a Lisp macro in `ob-table.el'.
| 
| (sbe SOURCE-BLOCK &rest VARIABLES)
| 
| Return the results of calling SOURCE-BLOCK with VARIABLES.
| Each element of VARIABLES should be a two
| element list, whose first element is the name of the variable and
| second element is a string of its value.  The following call to
| `sbe' would be equivalent to the following source code block.
| 
|  (sbe 'source-block (n $2) (m 3))
| 
| #+begin_src emacs-lisp :var results=source-block(n=val_at_col_2, m=3) :results silent
| results
| #+end_src
| 
| NOTE: by default string variable names are interpreted as
| references to source-code blocks, to force interpretation of a
| cell's value as a string, prefix the identifier a "$" (e.g.,
| "$$2" instead of "$2" or "$@2$2" instead of "@2$2").
| 
| NOTE: it is also possible to pass header arguments to the code
| block.  In this case a table cell should hold the string value of
| the header argument which can then be passed before all variables
| as shown in the example below.
