Java - Styling a TableView in CSS (JavaFX)

Styling a TableView in JavaFX involves using CSS (Cascading Style Sheets) to define the appearance of various components like rows, columns, headers, etc. Here's how you can style a TableView using CSS in JavaFX:

  1. Define CSS Styles: First, you need to define your CSS styles. You can do this in a separate CSS file or directly in your Java code if you prefer.

  2. Apply CSS Styles: Then, you apply these styles to your TableView using the setStyle() method or by adding a stylesheet to your JavaFX application.

Here's a basic example:

CSS Styling (styles.css):

/* Style the TableView */
.table-view {
    -fx-background-color: #f0f0f0;
}

/* Style the Table Header */
.table-view .column-header {
    -fx-background-color: #333;
    -fx-text-fill: white;
}

/* Style the Table Rows */
.table-view .table-row-cell {
    -fx-background-color: #ffffff;
}

/* Style the Table Row when hovered */
.table-view .table-row-cell:hover {
    -fx-background-color: #e0e0e0;
}

JavaFX Application:

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.TableColumn;
import javafx.scene.control.TableView;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;

public class TableViewStylingExample extends Application {

    @Override
    public void start(Stage primaryStage) {
        // Create a TableView
        TableView<String> tableView = new TableView<>();

        // Add columns
        TableColumn<String, String> column1 = new TableColumn<>("Column 1");
        TableColumn<String, String> column2 = new TableColumn<>("Column 2");
        tableView.getColumns().addAll(column1, column2);

        // Add some dummy data
        tableView.getItems().addAll("Row 1", "Row 2", "Row 3");

        // Apply CSS styles
        tableView.setStyle("-fx-background-color: transparent;");
        tableView.getStyleClass().add("table-view");

        // Load CSS
        Scene scene = new Scene(new VBox(tableView), 400, 300);
        scene.getStylesheets().add(getClass().getResource("styles.css").toExternalForm());

        primaryStage.setScene(scene);
        primaryStage.setTitle("TableView Styling Example");
        primaryStage.show();
    }

    public static void main(String[] args) {
        launch(args);
    }
}

In this example:

  • We define various CSS styles for the TableView, including the background color of the table, header, rows, and hover effect.
  • We create a TableView with some columns and data.
  • We apply the CSS styles to the TableView using setStyle() method and by adding the CSS stylesheet to the scene.

Ensure that you have your CSS file (styles.css) in the correct location and adjust the paths accordingly if needed.
