最终，我花了一整夜的时间编写代码：)好，感谢Clough先生提供的WAGU示例。
我的代码如下：
String company = "" + "V.K Autos Larkanan" + "Near Rehmaniya Masjid Larkanan" + "Police Shopping Center Larkanan" + "Cell: 0334-3269198, 0333-3910951n" + " n" + "CUSTOMER INVOICE" + " "; Calendar cal = Calendar.getInstance(); SimpleDateFormat sdf = new SimpleDateFormat("HH:mm:ss"); List<String> t1Headers = Arrays.asList("INFO", "CUSTOMER"); List<List<String>> t1Rows = Arrays.asList( Arrays.asList("DATE: " + date + "", "" + txt_cnam.getText()), Arrays.asList("TIME: " + sdf.format(cal.getTime()) + "", "Bill No:" + billno + "") ); String t2Desc = "SELLING DETAILS"; List<String> t2Headers = Arrays.asList("ITEM", "QTY", "Rate", "Total"); List<List<String>> t2Rows = new ArrayList<List<String>>(); for (int i = 0; i < tbl_sale.getRowCount(); i++) { String pid = tbl_sale.getValueAt(i, 0).toString(); String item = tbl_sale.getValueAt(i, 1).toString(); String quant = tbl_sale.getValueAt(i, 2).toString(); String rate = tbl_sale.getValueAt(i, 3).toString(); String rs = tbl_sale.getValueAt(i, 4).toString(); ArrayList<String> temp = new ArrayList<String>(); temp.add(item); temp.add(quant); temp.add(rate); temp.add(rs); t2Rows.add(temp); } List<Integer> t2ColWidths = Arrays.asList(16, 5, 7, 9); String t3Desc = "Sub Total"; List<String> t3Headers = Arrays.asList("", "", "", ""); List<List<String>> t3Rows = Arrays.asList( Arrays.asList("WR-DVD", "122.00", "7", "854.00") ); String summary = "" + "Sub Totaln"; String summaryVal = "" + txt_total.getText() + "n"; String sign1 = "" +"------Thank you for your visit------n"; String sign2 = "" + "-We value your visit-n"; String advertise = "******** Soulution by AbroSoft *******n* abrosoft@outlook.com # 03337584273 *"; try { Board b = new Board(48); b.setInitialBlock(new Block(b, 40, 6, company).allowGrid(true).setBlockAlign(Block.BLOCK_LEFT).setDataAlign(Block.DATA_CENTER)); b.appendTableTo(0, Board.APPEND_BELOW, new Table(b, 42, t1Headers, t1Rows)); b.getBlock(3).setBelowBlock(new Block(b, 40, 1, t2Desc).setDataAlign(Block.DATA_CENTER)); b.appendTableTo(5, Board.APPEND_BELOW, new Table(b, 40, t2Headers, t2Rows, t2ColWidths)); Block summaryBlock = new Block(b, 30, 1, summary).setDataAlign(Block.DATA_TOP_RIGHT); b.getBlock(10).setBelowBlock(summaryBlock); Block summaryValBlock = new Block(b, 9, 1, summaryVal).setDataAlign(Block.DATA_TOP_RIGHT); summaryBlock.setRightBlock(summaryValBlock); Block sign1Block = new Block(b, 40, 1, sign1).setDataAlign(Block.DATA_CENTER); b.getBlock(14).setBelowBlock(sign1Block); Block sign2Block = new Block(b, 40, 2, advertise).setDataAlign(Block.DATA_CENTER); b.getBlock(16).setBelowBlock(sign2Block); System.out.println(b.invalidate().build().getPreview());现在的输出就像我需要的:)。输出如下：
