我建议您从阅读How to Use Tables开始，您还可以从理解Dependency Injection和observer pattern等概念中受益
就我个人而言，我会从创建一个自定义的TableModel开始，它将接受数据源的一个示例（DatabaseLibros的一个示例）。为此，我会创建一个从AbstractTableModel扩展的类，这样你就可以轻松地配置和重用模型。
例如...

import java.awt.BorderLayout;
import java.awt.EventQueue;
import java.util.ArrayList;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JTable;
import javax.swing.table.AbstractTableModel;
public class Main {
    public static void main(String[] args) {
        new Main();
    }
    public Main() {
        EventQueue.invokeLater(new Runnable() {
            @Override
            public void run() {
                JFrame frame = new JFrame();
                frame.add(new TestPane());
                frame.pack();
                frame.setLocationRelativeTo(null);
                frame.setVisible(true);
            }
        });
    }
    public class TestPane extends JPanel {
        public TestPane() {
            setLayout(new BorderLayout());
            add(new JTable(new BookTableModel(new DatabaseLibros())));
        }
    }
    public class BookTableModel extends AbstractTableModel {
        private String[] columnNames = new String[]{
            "Título",
            "Autor",
            "Género",
            "ISBN"
        };
        private DatabaseLibros database;
        public BookTableModel(DatabaseLibros database) {
            this.database = database;
        }
        @Override
        public int getRowCount() {
            return database.obtenerLibros().size();
        }
        @Override
        public int getColumnCount() {
            return columnNames.length;
        }
        @Override
        public String getColumnName(int column) {
            return columnNames[column];
        }
        @Override
        public Object getValueAt(int rowIndex, int columnIndex) {
            Book book = database.obtenerLibros().get(rowIndex);
            switch (columnIndex) {
                case 0: return book.getTitle();
                case 1: return book.getAuthor();
                case 2: return book.getPublisher();
                case 3: return book.getIsbn();
            }
            return null;
        }
    }
    public class Book {
        private String title;
        private String author;
        private String publisher;
        private String isbn;
        public Book(String title, String author, String publisher, String isbn) {
            this.title = title;
            this.author = author;
            this.publisher = publisher;
            this.isbn = isbn;
        }
        public String getTitle() {
            return title;
        }
        public String getAuthor() {
            return author;
        }
        public String getPublisher() {
            return publisher;
        }
        public String getIsbn() {
            return isbn;
        }
    }
    public class DatabaseLibros {
        private ArrayList<Book> books = new ArrayList<>();
        public DatabaseLibros() {
            // Libro 1
            books.add(new Book("El señor de los anillos", "J.R.R. Tolkien", "Fantasía", "978-84-450-7570-9"));
            // Libro 2
            books.add(new Book("Cien años de soledad", "Gabriel García Márquez", "Realismo mágico", "978-84-376-0374-7"));
            // Libro 3
            books.add(new Book("1984", "George Orwell", "Distopía", "978-84-670-5189-7"));
        }
        // Método para obtener todos los libros de la base de datos
        public ArrayList<Book> obtenerLibros() {
            return books;
        }
        // Método para agregar un nuevo libro a la base de datos
        public void agregarLibro(Book nuevoBook) {
            books.add(nuevoBook);
        }
    }
}

作为一个旁注，我会小心使用static的方式，它很容易回来困扰你。
