如何从JTable向Excel或pdf添加“导出”功能？

Question

Edit: I've tried Apache POI, and successfully export it to excel by entering data manually but, i want to display data from my MYSQL database using JTable? any suggestion?

Here's my code:

public void showAllSchedule() {
    String[] kolom = { "title", "description", "date", "level" };

    dtm = new DefaultTableModel(null, kolom);
    try {
        Statement stmt = koneksi.createStatement();
        String query = "SELECT * FROM jadwal ORDER BY date ASC";
        ResultSet rs = stmt.executeQuery(query);
        while (rs.next()) {

            String title = rs.getString("title");
            String description = rs.getString("description");
            String date = rs.getString("date");
            String level = rs.getString("level");

            dtm.addRow(new String[] { title, description, date, level });
        }
    } catch (SQLException ex) {
        ex.printStackTrace();
    }
    main_table.setModel(dtm);
}

To write to excel you can use Apache POI .

There's also JXLS which is a library written on top of POI. It allows you to create a template spreadsheet which contains the logic (ie loops) to generate spreadsheets from a model.
