Is there a way to link or share a QTableWidgetItem between different QTableWidget

OK, let's see if I understand, I create a model that for example includes the Player Name, that would go in every Table Tab and will be the same so it's reflected in every Tab (view). Now I can add more to that base model right like sub-classes, right? So they all have Player Name but each Tab (view) has it's own Items.

You should have one model with columns you want to show in all the tabs and simply hide the columns you don't want to show in each of the views or alternatively use a filtering model which will hide the columns.
