TableDnD does not respect nodrag / nodrop when resorting dropped items

Situation:

I have a table with n rows, some of which are "locked". Rows which are locked should not be draggable nor should they allow drops. I have set class="nodrag nodrop" and added

onAllowDrop: function(draggee, droppee){

return (!isLocked(droppee.id));

},

to tableDnD().

If my locked items are something like this:

1 a

2 b

3 c LOCKED

4 d

5 e

when I go to drag for example row 4 to row 2, the "shuffling down" action will change the contents of row 3 so I will get:

1 a

2 d

3 b LOCKED

4 c

5 e

so as you see row 3 is changed via the "shuffling down", which seems to be caused from the mousemove method, by the parentNode.insertBefore method:

if (movingDown && jQuery.tableDnD.dragObject != currentRow) {

jQuery.tableDnD.dragObject.parentNode.insertBefore(jQuery.tableDnD.dragObject, currentRow.nextSibling);

} else if (! movingDown && jQuery.tableDnD.dragObject != currentRow) {

jQuery.tableDnD.dragObject.parentNode.insertBefore(jQuery.tableDnD.dragObject, currentRow);

}

This does not take into account the nodrag/nodrop "locked" state of various table rows.
