selecting columns to export

selecting columns to export

[Greg Minshall]

hi.  i have an org-mode table with a large number of columns, but would
like to export only a small number of them.  is there an obvious way of
doing this?

cheers, Greg

Put a partial echo code block (one where you select in the var header argument
which columns interest you), and output the results of that code block?

Best regards,

thanks!  below is the final result of your suggestion.  (my table was
long, so i had to use longtable; i also used a "landscape" documentclass
variant in order to hold more columns for printing.)

cheers, Greg
