Issue was, that the cellchange is triggered at re-sorting - so we need to check the names
Following issue was, that when removing or renaming something in re-sorted table - so there was a bug that referenced to the row instead of the index
Thought about to remove mIndexedWidgets completely, but when renumbering after delete in unsorted table, we cannot reference to the row order.
When sort and then toggle edditing, the problem was that it wanted to rename all the fields
Whis is avoided now by checking the indexes
But still problems open when one wants to rename fields in unsorted layout
in attribute form properties: editable and lable on top config to general
fix: in case that somebody deletes a field on sourcedata and then wants to change config on it in attribute - it's now disabled (but not updated)
fix: if adding new attribute after adding a virtual one, the display of the list was wrong (value of virtual in non-virtual row) - now it reloads the table correctly
