Java 实现在word或者pdf上 一页纸打印六块区域数据

    项目中有这样的需求,用户点击导出数据,然后将界面上的数据,打印在一张A4纸上,要求,一页纸有两行三列,每个块固定的格式数据,一开始还真不知道怎么下手,后面同事做了,使用了框架:iText,这个专门用来输出固定格式的word或者pdf,很是强大,不多说了,直接上代码,需要jar包为:itextpdf-5.3.4.jar,itext-asian.jar,如下具体的代码,有注释:

     一般输出pdf，其实是为了财务能将A4纸一些工资或者用户的东西进行裁剪，这就需要保证如果是两行两列，每行的高度需要固定，才能在指定的高度处进行裁剪，经过查找资料，原来的Cell类并没有提供固定高度的方法，只有pdfPcell可以的，如下示例代码设置A-Z26行，5列的表格，设置其中某些列为特殊高度：

import com.itextpdf.text.Document;import com.itextpdf.text.DocumentException;import com.itextpdf.text.Paragraph;import com.itextpdf.text.pdf.PdfPCell;import com.itextpdf.text.pdf.PdfPTable;import com.itextpdf.text.pdf.PdfWriter;import java.io.File;import java.io.FileOutputStream;import java.io.IOException;import sandbox.WrapToTest;@WrapToTestpublic class FixedHeightCell {public static final String DEST = "results/tables/fixed_height_cell.pdf";public static void main(String[] args) throws IOException,DocumentException {File file = new File(DEST);file.getParentFile().mkdirs();new FixedHeightCell().createPdf(DEST);}public void createPdf(String dest) throws IOException, DocumentException {Document document = new Document();PdfWriter.getInstance(document, new FileOutputStream(dest));document.open();PdfPTable table = new PdfPTable(3);//3代表几列的意思table.setWidthPercentage(100);PdfPCell cell;for (int r = 1; r <= 2; r++) {for (int c = 1; c <= 3; c++) {cell = new PdfPCell();cell.addElement(new Paragraph(String.valueOf((char) r)+ String.valueOf(c)));cell.setFixedHeight(285);// 控制每个输出的高度为A4纸上的一半高度}table.addCell(cell);}}document.add(table);document.close();}}

         参考的连接如下：http://developers.itextpdf.com/examples/tables-itext5/cell-heights，http://stackoverflow.com/questions/8266554/itext-set-cells-height，http://stackoverflow.com/questions/25279646/how-to-set-height-of-pdfptable-in-itextsharp。

        要注意的是：PdfPTable table = new PdfPTable(3);// 设置一行几列，然后循环遍历两次，就可以在一张A4纸上打印两行三列

    2017年3月17日15:46:47：更新，要有缩进的话，用如下代码：

Cell cell = new Cell();
Paragraph titleParagraph = new Paragraph();
titleParagraph.setAlignment(Paragraph.ALIGN_CENTER);
titleParagraph.setIndentationLeft(5);// 调整每个的间距：Indentation缩进
titleParagraph.setFont(fontChinese);
