The Add button works fine (although I do need to look at the part of the code you mentioned. I thought it was adding a table group and not the whole table as there was no header displayed after clicking the add button - just the group (two rows).
My apologies if I was unclear, just issues with the delete button and trying to figure out how to skip numbering.

Your add button seems to work with an extra .parent, so
Or you could just have
But the code in that add button click event also has the code "this.resolveNode('Table1._').addInstance(1);", which adds a whole new table. Is it meant to be there, without it the sequence numbering also works.
