itext实现复杂表格

  最近打算做日周月的质量分析报告，以便于发送给相应负责人查看质量现状。希望是可以生成pdf，并发送邮件的形式。
  此处采用itext来进行实现，demo代码中，table定义以及表头如下代码所示：
 

public static Table getInitTable() throws DocumentException {
		Table t = new Table(10, 2);
		int width[] = { 50, 50,20,40, 80, 50, 50, 50, 50, 60 };
		t.setWidths(width);
		t.setWidth(100); // 占页面宽度 %
		t.setPadding(1);
		t.setSpacing(0);
		t.setBorderWidth(1);

		Cell c1 = new Cell(new Phrase("应用", PdfUtils.GRAYFONT_CHINESE));
		c1.setRowspan(2);
		setAlignCenter(c1);
		t.addCell(c1);

		c1 = new Cell(new Phrase("指标", PdfUtils.GRAYFONT_CHINESE));
		c1.setColspan(3);
		setAlignCenter(c1);
		t.addCell(c1);
		

		c1 = new Cell(new Phrase("本期数据", PdfUtils.GRAYFONT_CHINESE));
		c1.setRowspan(2);
		setAlignCenter(c1);
		t.addCell(c1);
		c1 = new Cell(new Phrase("上期环比", PdfUtils.GRAYFONT_CHINESE));
		c1.setRowspan(2);
		setAlignCenter(c1);
		t.addCell(c1);
		c1 = new Cell(new Phrase("同期对比", PdfUtils.GRAYFONT_CHINESE));
		c1.setRowspan(2);
		setAlignCenter(c1);
		t.addCell(c1);
		c1 = new Cell(new Phrase("均值对比", PdfUtils.GRAYFONT_CHINESE));
		c1.setRowspan(2);
		setAlignCenter(c1);
		t.addCell(c1);
		c1 = new Cell(new Phrase("告警次数", PdfUtils.GRAYFONT_CHINESE));
		c1.setRowspan(2);
		setAlignCenter(c1);
		t.addCell(c1);
		c1 = new Cell(new Phrase("告警时长(分钟)", PdfUtils.GRAYFONT_CHINESE));
		c1.setRowspan(2);
		setAlignCenter(c1);
		t.addCell(c1);
		
		c1 = new Cell(new Phrase("字段", PdfUtils.GRAYFONT_CHINESE));
		setAlignCenter(c1);
		t.addCell(c1);
		c1 = new Cell(new Phrase("统计方式", PdfUtils.GRAYFONT_CHINESE));
		c1.setColspan(2);
		setAlignCenter(c1);
		t.addCell(c1);
		
		return t;
