On table edit, the labels update, but the values don't ever seem to, as whenever the table is updated the values revert. This happens with sorting, and can be shown to be true via: for(Row r : elementsTable.getItems().get(0)) System.out.println(r.getSymbol() + r.getWeight() + r.getAtom()); GUI: @FXML private TextField row1; @FXML private TextField row2; @FXML private TextField row3; @FXML private
