Double click or press F2

Tab

Click the row's label to select the row then press Del

Er, select a row then press Ins?
Select Row, Insert from a menu?

In place probably.

For this last case, as a programmer I find it a lot easier to use the 
latter approach for database applications where rows represent records 
in a database table. I find it harder to provide in-place editing, 
partly because of the issues you raised. For example, when updating a 
table of say exchange rates, as a user you'd want to enter a number, 
press *one* key to both move to the same column of the next row *and* 
start editing. I think this may be hard to do with JTable, especially 
when overriding the default cell editor with some other Swing widget.

I guess that it may depend on whether you want to give the user the 
illusion that the backing data store is being directly updated as they 
type or whether you want them to be aware of a row (record) as a unit of 
update.
