Answer 1

You can retrieve the default selection model when you create the table:
TableView<T> table = new TableView<>();
TableViewSelectionModel<T> defaultSelectionModel = table.getSelectionModel();
where T is the type for your table. (Of course, if you are using FXML, just put the second line in the controller's initialize() method.)
Then to disable row selection do
table.setSelectionModel(null);
and to enable it again
table.setSelectionModel(defaultSelectionModel);
Here is a SSCCE:
import java.util.function.Function;
import javafx.application.Application;
import javafx.beans.property.Property;
import javafx.beans.property.SimpleStringProperty;
import javafx.beans.property.StringProperty;
import javafx.geometry.Insets;
import javafx.geometry.Pos;
import javafx.scene.Scene;
import javafx.scene.control.CheckBox;
import javafx.scene.control.TableColumn;
import javafx.scene.control.TableView;
import javafx.scene.control.TableView.TableViewSelectionModel;
import javafx.scene.layout.BorderPane;
import javafx.stage.Stage;
public class TableWithDisabledSelection extends Application {
#Override
public void start(Stage primaryStage) {
TableView<Person> table = new TableView<>();
TableViewSelectionModel<Person> defaultSelectionModel = table.getSelectionModel();
table.getColumns().add(column("First Name", Person::firstNameProperty));
table.getColumns().add(column("Last Name", Person::lastNameProperty));
table.getColumns().add(column("Email", Person::emailProperty));
table.getItems().addAll(
new Person("Jacob", "Smith", "jacob.smith#example.com"),
new Person("Isabella", "Johnson", "isabella.johnson#example.com"),
new Person("Ethan", "Williams", "ethan.williams#example.com"),
new Person("Emma", "Jones", "emma.jones#example.com"),
new Person("Michael", "Brown", "michael.brown#example.com")
);
CheckBox enableSelection = new CheckBox("Enable selection");
enableSelection.setSelected(true);
enableSelection.selectedProperty().addListener((obs, wasSelected, isNowSelected) -> {
if (isNowSelected) {
table.setSelectionModel(defaultSelectionModel);
} else {
table.setSelectionModel(null);
}
});
BorderPane root = new BorderPane(table);
BorderPane.setAlignment(enableSelection, Pos.CENTER);
BorderPane.setMargin(enableSelection, new Insets(5));
root.setBottom(enableSelection);
primaryStage.setScene(new Scene(root, 600, 600));
primaryStage.show();
}
private <S,T> TableColumn<S,T> column(String title, Function<S,Property<T>> prop) {
TableColumn<S,T> col = new TableColumn<>(title);
col.setCellValueFactory(cellData -> prop.apply(cellData.getValue()));
return col ;
}
public static void main(String[] args) {
launch(args);
}
public static class Person {
private final StringProperty firstName = new SimpleStringProperty();
private final StringProperty lastName = new SimpleStringProperty();
private final StringProperty email = new SimpleStringProperty();
public Person(String firstName, String lastName, String email) {
setFirstName(firstName);
setLastName(lastName);
setEmail(email);
}
public final StringProperty firstNameProperty() {
return this.firstName;
}
public final String getFirstName() {
return this.firstNameProperty().get();
}
public final void setFirstName(final String firstName) {
this.firstNameProperty().set(firstName);
}
public final StringProperty lastNameProperty() {
return this.lastName;
}
public final String getLastName() {
return this.lastNameProperty().get();
}
public final void setLastName(final String lastName) {
this.lastNameProperty().set(lastName);
}
public final StringProperty emailProperty() {
return this.email;
}
public final String getEmail() {
return this.emailProperty().get();
}
public final void setEmail(final String email) {
this.emailProperty().set(email);
}
}
}

Answer 2

I handled this situation with rowfactory like this;
tableView.setRowFactory(param -> new TableRow<Model>()
{
#Override
protected void updateItem(Model item, boolean empty)
{
super.updateItem(item, empty);
if (!empty)
{
disableProperty().bind(item.getFocusable().not());
}
}
});
so, you can bind the disableproperty with suitable property of your tableview model.
