How to populate TableView dynamically with FXML an

How do I define my table in FXML and then use my JavaFX code to populate it dynamically at runtime?

Define the TableView in the fxml file. Few things to note:
- the root should have a controller class associated with it.
- the TableView and TableColumn should have fx:id attributes specified.

<BorderPane xmlns:fx="http://javafx.com/fxml" fx:controller="com.example.MyController"> <center> <ScrollPane disable="false" visible="true"> <content> <TableView fx:id="myTableView" prefHeight="-1.0" prefWidth="-1.0"> <columns> <TableColumn fx:id="idColumn" prefWidth="100.0" text="Id" /> </columns> </TableView> </content> </ScrollPane> </center> </BorderPane>

Define the controller class. Few things to note:
- the variables should be linked with the @FXML tag and a new object of TableView/TableColumn should not be created.
- the variables should be named the same as the corresponding attribute value of fx:id as mentioned in the fxml.
- the controller class should implement javafx.fxml.Initializable and hence should define the method public void initialize(URL location, ResourceBundle resources)
- a class Data Model class MyDataModel is used to populate the data.
  
  public class MyController implements Initializable {
```
@FXML
private TableView<MyDataModel> myTableView;

@FXML
private TableColumn<MyDataModel, String> idColumn;

@Override
public void initialize(URL location, ResourceBundle resources) {
idColumn.setCellValueFactory(new PropertyValueFactory<MyDataModel, String>"idColumn"));

myTableView.getItems().setAll(getItemsToAdd());
}

private List<MyDataModel> getItemsToAdd(){
// this method would fetch the necessary items from database.
}
```
  }
Define the Data Model class. Few things to note:
- the variable should be named as idColumnProperty as the string passed for PropertyValueFactory is "idColumn".
- the variable must be private final SimpleStringProperty as the type mentioned in controller class is String for the column.
- the model class must have the methods getIdColumn() and setIdColumn(String id)
  
  public class MyDataModel {
```
private final SimpleStringProperty idColumnProperty = new SimpleStringProperty("");

public MyDataModel(){
this("");
}

public MyDataModel(String id){
setIdColumn(id);    
}

public String getIdColumn(){
idColumnProperty.get();
}

public void setIdColumn(String id){
idColumnProperty.set(id);
}
```
  }
