I did not find a builtin feature of grid to make that, but can think of two
ways of doing this
a) Using virtual fields and the grid fields argument.
b) Using helper methods for customizing the table
I think b) is more simple to code but can have less performance than a)
b)
grid = SQLFORM.grid(query or table)
trs = grid.element("table").elements("tr")
grid.element("thead").insert(0, TH(<name>))
for i, tr in enumerate(grid.element("tbody").elements("tr")):
tr.insert(0, TD(i+1))
a) is just about setting a virtual field for the table with a record
counter and specifying it in the grid fields argument .
Also, as you can see, this field should NOT be viewed in update or create
> mode.

Perhaps you could read the request arguments so you can enable/disable the
row count when there was a record edit/update requested.
