JavaFX TableView text alignment

JavaFX TableView text alignment

In JavaFX, you can set the text alignment for columns in a TableView by using cell factories and styles. You can align the text within individual cells of a TableView column according to your requirements. Here's how you can achieve text alignment for columns in a JavaFX TableView:

Let's say you have a TableView with a column named "Name," and you want to align the text within that column to the right. Here's how you can do it:

  1. Create a TableView:

    First, create a TableView and add a column to it.

    TableView<Person> tableView = new TableView<>(); TableColumn<Person, String> nameColumn = new TableColumn<>("Name"); nameColumn.setCellValueFactory(new PropertyValueFactory<>("name")); tableView.getColumns().add(nameColumn);

  2. Set Cell Factory for the Column:

    To customize the cell rendering, you need to set a cell factory for the column. In this case, you can create a custom TableCell implementation that sets the text alignment to right.

    nameColumn.setCellFactory(column -> { return new TableCell<Person, String>() { @Override protected void updateItem(String item, boolean empty) { super.updateItem(item, empty); if (item == null || empty) { setText(null); setStyle(""); // Clear any previous styles } else { setText(item); setAlignment(Pos.CENTER_RIGHT); // Set text alignment to right } } }; });

  3. Set Data to the TableView:

    Populate your TableView with data. In this example, we assume you have a Person class with a name property.

    ObservableList<Person> data = FXCollections.observableArrayList( new Person("John"), new Person("Alice"), // Add more persons here ); tableView.setItems(data);

  4. Display the TableView:

    Finally, add the TableView to your JavaFX scene and show it.

    Scene scene = new Scene(new BorderPane(tableView), 800, 600); primaryStage.setScene(scene); primaryStage.show();

With the above code, the text within the "Name" column of your TableView will be right-aligned. You can adjust the setAlignment(Pos.CENTER_RIGHT) line to change the alignment as needed, such as Pos.CENTER_LEFT for left alignment or Pos.CENTER for center alignment.
