Hello,
I have been writing a derived backend for LaTeX export which outputs the
formulae used in a table. This is for teaching purposes where I
currently use an external spreadsheet to illustrate some simple
modelling concepts. I would prefer to use org (as my slides are
generated by org via beamer) and am able to output a formatted table of
the formulae used in a table.
However, due to various possible hidden rows and columns that do not
appear in the exported table, the row and column references are not
easily usable directly to identify the reference entries in the table.
Would it be possible to extend the table-cell element in the parser to
add :row and :column attributes that have the internal org values, as
used by the formulae?
An example table that I have been using to test my derived backend and
which illustrates the issue is:
#+begin_src org
| | Strategy | Average performance |
|---+----------+---------------------|
| / | | 8.69 |
| / | | 9.72 |
| / | | 9.03 |
|---+----------+---------------------|
| | 1 | 9.15 |
|---+----------+---------------------|
| / | | 9.15 |
| / | | 7.60 |
| / | | 7.46 |
|---+----------+---------------------|
| | 2 | 8.07 |
|---+----------+---------------------|
,#+TBLFM: @5$3=vmean(@-I..@-II);%.2f::@9$3=vmean(@-I..@-II);%.2f
#+end_src
This table does not export the first column nor any of the rows with /
in the first column. So, in the exported table, there are only 3 rows
and 2 columns but the formulae refer to, e.g. column 3 and row 9. I
would like to be able to annotate the output with the org row and column
numbers so need access to these data.
A screenshot of what the derived backend generates currently is attached.
thanks,
eric

I don' think this is needed since this information is readily available
during the export process. For example
(1+ (length (org-export-get-previous-element table-cell info 'all)))
returns the column number table-cell belongs to, whereas
(1+ (cl-count-if
(lambda (row) (eq (org-element-property :type row) 'standard))
(org-export-get-previous-element (org-export-get-parent table-cell) 'all)))
returns the row number.

Ah, okay. Sounds good. Counting each time seems inefficient at first
glance but I guess it's not a real issue, especially in my case where
the tables are all quite small. I'll give this a try tomorrow.
Thanks,

Well, this returns the column number in the elided table, not the
original table. In other words, after columns have been removed before
processing for export.
I need the row and column numbers in the original table in the org file,
not what is actually exported!

And this one gives me an error which I do not understand:
,----
| Debugger entered--Lisp error: (wrong-type-argument listp table-row)
| org-element-property(:type table-row)
| (eq (org-element-property :type row) (quote standard))
| (lambda (row) (eq (org-element-property :type row) (quote standard)))(table-row)
| cl-count(nil (table-row (:type rule :begin 76 :end 96 :contents-begin nil [...]
| apply(cl-count nil (table-row (:type rule :begin 76 :end 96 [...]
| cl-count-if((lambda (row) (eq (org-element-property :type row) [...]
`----
Any suggestions very welcome!
Thanks,
eric
