Report showing the position of an event within a set of event results

Is there a way to report on the position of an event relative to the rest of the events in the result set?

For example, if I have five events in my result set, is there a way to display each event along with the position number relative in time to the other events, kind of like showing the ordering or row number?

Like this:

User     Row_Position
----     ------------
Eric     1

Greg     2

Gerald   3

Ledio    4

Mick     5

where the event containing the User=Eric is the earliest in time, the one with User=Greg is second one in time after that one, the event with User=Gerald is the next event in time after that one, etc.

BTW, when I create a table with my search, I notice a grayed-out row number on the far left side of the table in the search results page. Can I reference that? If so, what is the name of that field?
