When I export a report from Access, the Excel files has two (extra) columns
(in line with the Column identifiers A, B, C, etc.), marked with a "1" and
"2", on the far left of the worksheet. Clicking on the "1" collapses the
data so I can't see it anymore, and clicking on the "2", restores it so that
it is visible.

1. How do I remove this feature from my Excel file?
2. What is the purpose of this feature?
3. How would I lookup this feature in Excel "Help"?1

Thanks,
Bernie
