[O] working with delimited files

[Sivaram Neelakantan]

I sometimes work with files looking like this

BEL EQ 13-Jan-2006 978.85 988.9 1050 983 1025 1024.5 1025.94 276666 2838.429191
BEL EQ 16-Jan-2006 1024.5 1030 1043 1001.5 1003.5 1008.65 1027.02 72409 743.655
BEL EQ 17-Jan-2006 1008.65 1010 1030 985.1 993.75 989.95 1013.83 102589 1040.07
BEL EQ 18-Jan-2006 989.95 984 1006.8 963.6 1002.15 999.45 990.75 94266 933.9413

When I have a few thousand rows like this, this becomes difficult to
read, so I tend to

a) M-x org-mode
b) C-x h followed by C-c |

This makes it easier to read as you can see below
| BEL | EQ | 02-Jan-2006 |  993.15 |     998 |    1001 |     983 |..
| BEL | EQ | 03-Jan-2006 |  989.05 |   999.5 |    1000 |   989.9 |..
| BEL | EQ | 04-Jan-2006 |  994.35 |     998 |    1014 |  986.15 |..

How do I use the overlay for editing but keep the underlying file
structure?  If I do an C-C C-e, I get unnecessary headers and the
fields are tabbed out and I have to save it as a different
file. Ideally, I'd like to keep the file structure as it is and just
use org-mode to provide viewing structure while editing.
