Kajian 2 - JTable

JTable digunakan untuk menampilkan data dalam bentuk tabel, suatu bentuk yang banyak digunakan dalam pemrograman database.

berikut contoh sintaknya :

import java.awt.event.ActionEvent;

import java.awt.event.ActionListener;

import javax.swing.*;

import javax.swing.table.*;

public class table extends JFrame implements ActionListener {

            DefaultTableModel tableModel = new DefaultTableModel();

            JTable table = new JTable();

            JButton bt1 = new JButton("Tambah Baris Kosong");

            JButton bt2 = new JButton("Tambah Baris");

            public table() {

                        setTitle("Contoh Penggunaan JTable");

                        setSize(600, 500);

                        setLocationRelativeTo(null);

                        setDefaultCloseOperation(EXIT_ON_CLOSE);

                        buatTampilan();

                        setVisible(true);

            }

            void buatTampilan() {

                        table.setModel(tableModel);

                        tableModel.addColumn("Kolom 1");

                        tableModel.addColumn("Kolom 2");

                        tableModel.addColumn("Kolom 3");

                        tableModel.addColumn("Kolom 4");

                        tableModel.addRow(new Object[] { "Data Kolom 0 Baris 0",

                                                "Data Kolom 1 Baris 0", "Data Kolom 2 Baris 0",

                                                "Data Kolom 3 Baris 0" });

                        tableModel.addRow(new Object[] { "Data Kolom 0 Baris 1",

                                                "Data Kolom 1 Baris 1", "Data Kolom 2 Baris 1",

                                                "Data Kolom 3 Baris 1" });

                        tableModel.addRow(new Object[] { "Data Kolom 0 Baris 2",

                                                "Data Kolom 1 Baris 2", "Data Kolom 2 Baris 2",

                                                "Data Kolom 3 Baris 2" });

                        JScrollPane scroll = new JScrollPane();

                        scroll.getViewport().add(table);

                        JPanel panel = new JPanel();

                        panel.add(bt1);

                        bt1.addActionListener(this);

                        panel.add(bt2);

                        bt2.addActionListener(this);

                        getContentPane().add(panel, "North");

                        getContentPane().add(scroll);

            }

            public static void main(String[] args) {

                        new table();

            }

            public void actionPerformed(ActionEvent e) {

                        if (e.getSource() == bt1) {

                                    tableModel.addRow(new Object[] {});

                        } else if (e.getSource() == bt2) {

                                    int i = tableModel.getRowCount();

                                    tableModel.addRow(new Object[] { "Data Kolom 0 Baris " + i,

                                                            "Data Kolom 1 Baris " + i, "Data Kolom 2 Baris " + i,

                                                            "Data Kolom 3 Baris " + i });

                        }

            }
