Javafx TableView in a ScrollPane - javafx

Question

I'm having some issues with the Constrained Resize Policy for a TableView inside a ScrollPane.
It seems as though the headings do not line up completely with its column. On scroll or resize the columns snap to their correct position.
I created a small example to demonstrate:
import java.util.ArrayList;
import javafx.application.Application;
import javafx.beans.property.SimpleStringProperty;
import javafx.beans.property.StringProperty;
import javafx.collections.FXCollections;
import javafx.scene.Scene;
import javafx.scene.control.ScrollPane;
import javafx.scene.control.TableColumn;
import javafx.scene.control.TableView;
import javafx.scene.control.cell.PropertyValueFactory;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;
public class Test extends Application
{
public static void main(String[] args) throws Exception
{
launch(args);
}
#Override
public void start(Stage primarystage) throws Exception
{
// Create layout
VBox root = new VBox();
TableView<TableObject> table = new TableView<TableObject>();
TableColumn<TableObject, String> col1 = new TableColumn<TableObject, String>("Column 1");
TableColumn<TableObject, String> col2 = new TableColumn<TableObject, String>("Column 2");
table.getColumns().addAll(col1, col2);
col1.setCellValueFactory(new PropertyValueFactory<TableObject, String>("column1"));
col2.setCellValueFactory(new PropertyValueFactory<TableObject, String>("column2"));
table.setColumnResizePolicy(TableView.CONSTRAINED_RESIZE_POLICY);
root.getChildren().add(table);
ScrollPane scrollpane = new ScrollPane();
scrollpane.setFitToWidth(true);
scrollpane.setFitToHeight(true);
scrollpane.setPrefSize(500, 200);
scrollpane.setContent(root);
// Create and show scene
Scene scene = new Scene(scrollpane);
primarystage.setScene(scene);
primarystage.show();
// Populate table
ArrayList<TableObject> data = new ArrayList<TableObject>();
for (int i = 0; i < 20;)
{
TableObject entry = new TableObject(String.valueOf(i++), String.valueOf(i++));
data.add(entry);
}
table.setItems(FXCollections.observableArrayList(data));
}
public class TableObject
{
private StringProperty column1;
private StringProperty column2;
public TableObject(String col1, String col2)
{
column1 = new SimpleStringProperty(col1);
column2 = new SimpleStringProperty(col2);
}
public StringProperty column1Property()
{
return column1;
}
public StringProperty column2Property()
{
return column2;
}
}
}
The result is this:
Is there perhaps something I am missing here?
Thanks

just show the stage after setting table items:
stage.show();
table.setItems(FXCollections.observableArrayList(data));
