Binding Map with TableView

Question

Hi,
I have a Map<String,String> which i want to display in a TableView with 2 colums(Key column and Value column). I am able to display the data by creating an ObservableList of objects having the key and value attributes but i want to bind the Map with the TableView. I have not come across anything related to this yet. Please help,
Thanks,
Avinash

This is working for me.
public class Table extends TableView<Map.Entry> {
    public Table() {
        super();
        setEditable(true);
        setColumnResizePolicy(TableView.CONSTRAINED_RESIZE_POLICY);
        buildColumns();
        populate();
    private void buildColumns() {
        TableColumn<Map.Entry, String> nCol = new TableColumn<Map.Entry, String>("Name");
        nCol.setEditable(true);
        nCol.setCellFactory(new Callback<TableColumn<Map.Entry, String>, TableCell<Map.Entry, String>>() {
            @Override
            public TableCell<Entry, String> call(TableColumn<Entry, String> param) {
                return new CustomTableCell();
        nCol.setCellValueFactory(new Callback<TableColumn.CellDataFeatures<Entry, String>, ObservableValue<String>>() {
            @Override
            public ObservableValue<String> call(CellDataFeatures<Entry, String> param) {
                String key = (String) param.getValue().getKey();
                return new SimpleObjectProperty<String>(key);
        TableColumn<Map.Entry, String> vCol = new TableColumn<Entry, String>("Value");
        vCol.setEditable(true);
        vCol.setCellFactory(new Callback<TableColumn<Entry, String>, TableCell<Entry, String>>() {
            @Override
            public TableCell<Entry, String> call(TableColumn<Entry, String> param) {
                return new CustomTableCell();
        vCol.setCellValueFactory(new Callback<CellDataFeatures<Entry, String>, ObservableValue<String>>() {
            @Override
            public ObservableValue<String> call(CellDataFeatures<Entry, String> param) {
                String value = (String) param.getValue().getValue();
                return new SimpleStringProperty(value);
        getColumns().setAll(nCol, vCol);
    private void populate() {
        Map<String, String> data = new HashMap<String, String>();
        data.put("a", "aa");
        data.put("b", "bb");
        data.put("c", "cc");
        data.put("d", "dd");
        Set<Entry<String, String>> dataSet = data.entrySet();    
        ObservableList tableData = FXCollections.observableArrayList(dataSet);
        setItems(tableData);
}The binding is still pending.
