Does not work with field collection module

The "Rebuild Table" function does not work when embeded in a field_collection module as a tablefield.

Testing scene:
1: config a field_collection field in one content type, and set number of values as "Unlimited".
2: add a tablefield to field_colledtion.
3: create a content, edit the tablefield just added and add another item.
4: Rebuild Table shows error.
