instead of using an array you could use a key/value object.
then you can do something like
var o = {}
o[row_position] = [row_data]
then when you remove a row you do
delete o[row_position]
you could get the row's position from the drag&drop callback I assume,
but even if thats not the case its pretty straight forward using
jquery i guess.
