@placeba Your newly added test is failing, otherwise looks good. Please fix your test case and happy to merge.

@ivailop7 $deleteCellHandler removes a table in a selection and then tries to select next node (nextNode.selectStart()).
The test fails because Firefox cannot handle with a new selection.

I can suggest removing these lines:

  if (nextNode) {
	nextNode.selectStart();
  } else {
	parentNode.selectStart();
  }

[ivailop7]

This fix is actually a bit more involved. Your solution breaks deletion for a few patterns, if you have text and table is the very last node, the editor crashes. If you have the table in the middle of the text, Ctrl + A, delete, it doesn't delete all the text outside of the table. If table is the first node and followed by text, Ctrl +A, delete also doesn't delete cleanly.

@ivailop7 Removing the node selection after deleting, as @placeba suggested, should do it.
