好的，这是一个非常基本的示例……
JTable通过各种print方法，已经支持打印了，基本上，这归结为获取JTable Printable
接口实例并将其传递给打印API，该API需要Graphics2D上下文来绘制……
奇怪的是，您具有Graphics2D上下文，因此这里的技巧是“充当”打印机并自己调用JTable的Printable print方法…
DefaultTableModel model = new DefaultTableModel(0, 10);for (int row = 0; row < 400; row++) { Object[] values = new Object[10]; for (int col = 0; col < 10; col++) { values[col] = ((char) ('A' + col)) + "x" + row; } model.addRow(values);}JTable table = new JTable(model);table.setSize(table.getPreferredSize());JTableHeader tableHeader = table.getTableHeader();tableHeader.setSize(tableHeader.getPreferredSize());document doc = new document(new Rectangle(1350, 1450));PdfDestination pdfDest = new PdfDestination(PdfDestination.XYZ, 0, 800, 0.50f);SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");java.util.Date date = new java.util.Date();String generatedDate = formatter.format(date);Paper paper = new Paper();paper.setSize(1350, 1450);paper.setImageableArea(10, 10, 1350 - 20, 1450 - 20);PageFormat pf = new PageFormat();pf.setPaper(paper);Printable printable = table.getPrintable(JTable.PrintMode.NORMAL, null, null);try { PdfWriter writer; writer = PdfWriter.getInstance(doc, new FileOutputStream("test.pdf")); writer.setViewerPreferences(PdfWriter.PageLayoutSinglePage); doc.open(); // Use this to "test" if there is page // available for printing, otherwise it prints // a empty page and I can't figure out // how to remove it :P BufferedImage img = new BufferedImage(1, 1, BufferedImage.TYPE_INT_ARGB); Graphics2D g = img.createGraphics(); Font f = new Font(Font.TIMES_ROMAN, 12f); int page = 0; int result = Printable.NO_SUCH_PAGE; PdfContentByte cb = writer.getDirectContent(); do { result = printable.print(g, pf, page); if (result == Printable.PAGE_EXISTS) { cb.saveState(); Graphics2D g2 = cb.createGraphics(1350, 1450); System.out.println(page); result = printable.print(g2, pf, page); g2.dispose(); cb.restoreState(); doc.add(new Paragraph("REPORTS", f)); doc.add(new Paragraph("document Generated On - " + generatedDate, f)); page++; doc.newPage(); } } while (result == Printable.PAGE_EXISTS); g.dispose();} catch (documentException | PrinterException | FileNotFoundException e) { e.printStackTrace();} finally { doc.close();}现在，我需要显示表以便显示行标题，但是可能还有其他解决方法。
