[O] [babel] feature request: extracting non-sequential columns and/or rows from a table

[Eric S Fraga]

Hello,

this is a very low priority request so please feel free to ignore or put
at the bottom of what I'm sure is a long list of TODOs...

I have a data table.  In different code blocks, I need to access
different sets of columns (or rows) from this table.  At present, I am
passing the whole table to the code blocks and then extracting the
columns (or rows) within the code.  However, it would be nice if I could
specify the actual column I want directly in the :var header argument,
such as

:  #+begin_src octave :var data=mytable[0:-1;1:3,5:6]

where I've used a semi-colon to separate dimension indices and used a
comma to separate multiple ranges within an index.  This, I realise, is
a change to the current syntax... but I'm doing this just for
illustration.

As I said, I have a workaround so this is indeed a low priority request!

Thanks,
eric
