Does this multi-line form interface pattern have a name?

I've got a form where the user needs to enter a number of records (varies for each screen), and the UI approach I'm considering is to have multiple rows, with the ability to add and remove rows, something akin to:

    -------- -------- X
    -------- -------- X
 +  -------- -------- X

Where clicking + adds another row, and clicking X removes a particular row. I'm interested to know of there are any names for this pattern so I can find appropriate documentation for the app framework we're using to develop it (it's a somewhat clunky RAD framework - so we've got a bit of work to do to make it do what we need).
