如果使用ObservableMaps的ObservableList作为您的TableView的数据结构

  ObservableList< ObservableMap> rowMaps = FXCollections.observableArrayList（）; 
 tableView.setItems（rowMaps）; 
 

并实现您自己的ObservableMapValueFactory

  import javafx.beans.property.ObjectProperty; 
 import javafx.beans.property.SimpleObjectProperty; 
 import javafx.beans.value.ObservableValue; 
 import javafx.collections.MapChangeListener; 
 import javafx.collections.ObservableMap; 
 import javafx.scene.control.TableColumn; 
 import javafx.scene.control.TableColumn.CellDataFeatures; 
 import javafx.util.Callback; 

 public class ObservableMapValueFactory< V>实现
回调< TableColumn.CellDataFeatures< ObservableMap，V>，ObservableValue< V> {

 private final Object key; 

 public ObservableMapValueFactory（Object key）{
 this.key = key; 
} 

 @Override 
 public ObservableValue< V>调用（CellDataFeatures< ObservableMap，V> features）{
 final ObservableMap map = features.getValue（）; 
 final ObjectProperty< V> property = new SimpleObjectProperty< V>（（V）map.get（key））; 
 map.addListener（new MapChangeListener< Object，V>（）{
 public void onChanged（更改<？，？扩展V>更改）{
 if（key.equals（change.getKey （）））{
 property.set（（V）map.get（key））; 
} 
} 
}）; 
返回属性;

然后将其设置为单元格值工厂列（s）
  column.setCellValueFactory（new ObservableMapValueFactory< String>（columnId））; 
 
您的数据的所有更改都反映在TableView中，甚至只会影响ObservableMaps的更改。
 
Suppose that I have a map collection:
ObserableHashMap<K,V> map = FXCollections.observableHashMap();

I put 1 record into this map during fxml controller initialization, then wrap it as ObservableList:
ObservableList<ObserableHashMap.Entry<K,V>> list = FXCollections.observableArrayList(map.entrySet());

then setitems for my tableView.setItems(list);

Everything is fine when I run this JavaFX app and 1 record is showing.

Question is that:

When I add more records later to my map, my TableView will not refresh these records.

How could I bind a dynamical map collection into my TableView?

Thanks

If you use an ObservableList of ObservableMaps as your TableView's data structure
ObservableList<ObservableMap> rowMaps = FXCollections.observableArrayList();
tableView.setItems(rowMaps);

and implement your own ObservableMapValueFactory
import javafx.beans.property.ObjectProperty;
import javafx.beans.property.SimpleObjectProperty;
import javafx.beans.value.ObservableValue;
import javafx.collections.MapChangeListener;
import javafx.collections.ObservableMap;
import javafx.scene.control.TableColumn;
import javafx.scene.control.TableColumn.CellDataFeatures;
import javafx.util.Callback;

public class ObservableMapValueFactory<V> implements
        Callback<TableColumn.CellDataFeatures<ObservableMap, V>, ObservableValue<V>> {

    private final Object key;

    public ObservableMapValueFactory(Object key) {
        this.key = key;
    }

    @Override
    public ObservableValue<V> call(CellDataFeatures<ObservableMap, V> features) {
        final ObservableMap map = features.getValue();
        final ObjectProperty<V> property = new SimpleObjectProperty<V>((V) map.get(key));
        map.addListener(new MapChangeListener<Object, V>() {
            public void onChanged(Change<?, ? extends V> change) {
                if (key.equals(change.getKey())) {
                    property.set((V) map.get(key));
                }
            }
        });
        return property;
    }
}

and then set it as the cell value factory for your column(s)
column.setCellValueFactory(new ObservableMapValueFactory<String>(columnId));

all changes to your data are reflected in the TableView, even changes only affecting the ObservableMaps.
