取消选中Javafx tableview复选框，禁用同一行但不同列的按钮

Question

Below image explains how I have populated my table:

As you can see, I need to disable the Installments column button once the Collected column checkbox of related row is unchecked and vise versa.

Here is my approach so far :

colected_column.setCellValueFactory((TableColumn.CellDataFeatures<Member, CheckBox> param) -> {
        Member mRow = param.getValue(); // type objects contained within the TableView
        CheckBox checkBox = new CheckBox();
        checkBox.selectedProperty().addListener((ov, old_val, new_val) -> {

            // javafx.scene.control.Button typed ObservableValue returns as cell value
            Button button = installments_column.getCellData(mRow);
            button.setDisable(!new_val);
        });

      ...
      return new SimpleObjectProperty<>(checkBox);
}

But this approach does not meet the requirement, button stays enable all the time. Any help would be appreciable. Thank you.

Don't put nodes in your item class. This way you ruin the main benefit of TableView : limiting the amount of nodes to the one it needs to display the content.

You should better use a BooleanProperty in your Member object, use CheckBoxTableCell to display the CheckBox es and use custom cells for the installments column:

TableColumn<Member, Boolean> colected_column = ...;

colected_column.setCellValueFactory((TableColumn.CellDataFeatures<Member, Boolean> param) -> {
    Member mRow = param.getValue(); // type objects contained within the TableView
    return nRow.collectedProperty();
});
colected_column.setCellFactory(CheckBoxTableCell.forTableColumn(colected_column));

TableColumn<Member, Boolean> installmentsColumn = ...;
installmentsColumn.setCellValueFactory(cd -> cd.getValue().collectedProperty());
installmentsColumn.setCellFactory(column -> new TableCell<Member, Boolean>() {

    private final Button button = new Button("View Info");

    {
        button.setOnAction(evt -> {
            Member member = (Member) getTableRow().getItem();

            // TODO: handle button click
        });
    }

    @Override
    protected void updateItem(Boolean item, boolean empty) {
        super.updateItem(item, empty);

        if (empty || item == null) {
            setGraphic(null);
        } else {
            setGraphic(button);
            button.setDisable(!item);
        }
    }
});

public class Member {
    private final BooleanProperty collected = new SimpleBooleanProperty(true);

    public void setCollected(boolean value) {
        collected.set(value);
    }

    public boolean isCollected() {
        return collected.get();
    }

    public BooleanProperty collectedProperty() {
        return collected;
    }

    ...
}
