[ic] Export Specific Columns and Rows

[interchange-users@icdevgroup.org (Jon)]

    Can someone provide a sample code snippet to export specific
rows and specific columns from a table. I've read about the export tag
which appears to assume you want to export the entire table; all rows
and columns.
And I've searched the archives for which there is a lot of discussion
but I didn't find what I'm looking for there either.  An example would
be real helpful.   Thanks !

Jon
