Compressing table after DELETE ?? - Thanks for help

I have a table with a column of type number. This column is a form of keying mechanism, in that the keys are the row numbers. That is, rows 1 through 10 have keys 1 through 10. I always want this to be the case.

Two questions:

1. How do I maintain this after deleting a single row with a single DELETE statement?
2. How do I maintain this after deleting multiple rows with a single DELETE statement?
