iText - 合并单元格
?
iText中的PdfPTable和PdfPCell仅提供了合并列的功能（通过cell.setColspan(cellCount)实现），并未提供合并行的方法。如果需要生成下列表格，怎么实现呢？

可考虑在cell中添加一个表格来实现。对于上列表格，需先建立一个2列的表格。在表格的第一列中填充一个2行的表格即可。具体代码如下：

1 package itext; 2 3 import java.io.FileOutputStream; 4 5 import com.lowagie.text.Element; 6 import com.lowagie.text.PageSize; 7 import com.lowagie.text.Paragraph; 8 import com.lowagie.text.pdf.PdfPCell; 9 import com.lowagie.text.pdf.PdfPTable;10 import com.lowagie.text.pdf.PdfWriter;11 12 public class MergeCell {13 14 public static void main(String[] args) {15 String tmpPath = "c:\\test.pdf";16 PdfPCell cell;17 PdfPCell iCell;18 PdfPTable iTable;19 float lineHeight1 = (float)25.0;20 float lineHeight2 = (float)25.0; 21 try{22 Document pdfDoc = new Document(PageSize.A4.rotate(), 36, 36, 24, 36);23 24 PdfWriter.getInstance(pdfDoc, new FileOutputStream(tmpPath)); 25 26 pdfDoc.open();27 28 PdfPTable headerTable = new PdfPTable(2);29 headerTable.setWidthPercentage(40);30 31 //create a table to fill cell 132 iTable = new PdfPTable(2);33 iCell = new PdfPCell(new Paragraph("A"));34 iCell.setHorizontalAlignment(Element.ALIGN_CENTER);35 iCell.setVerticalAlignment(Element.ALIGN_MIDDLE);36 iCell.setFixedHeight(lineHeight1);37 //merge column38 iCell.setColspan(2);39 iTable.addCell(iCell);40 iCell = new PdfPCell(new Paragraph("B"));41 iCell.setHorizontalAlignment(Element.ALIGN_CENTER);42 iCell.setVerticalAlignment(Element.ALIGN_MIDDLE);43 iCell.setFixedHeight(lineHeight2);44 iTable.addCell(iCell);45 iCell = new PdfPCell(new Paragraph("C"));46 iCell.setHorizontalAlignment(Element.ALIGN_CENTER);47 iCell.setVerticalAlignment(Element.ALIGN_MIDDLE);48 iCell.setFixedHeight(lineHeight2);49 iTable.addCell(iCell);50 cell = new PdfPCell(iTable);51 cell.setPadding(0);52 headerTable.addCell(cell); 53 54 //fill cell 255 cell = new PdfPCell(new Paragraph("D"));56 cell.setHorizontalAlignment(Element.ALIGN_CENTER);57 cell.setVerticalAlignment(Element.ALIGN_MIDDLE);58 cell.setPadding(0);59 cell.setFixedHeight(lineHeight1+lineHeight2);60 headerTable.addCell(cell); 61 62 pdfDoc.add(headerTable);63 64 pdfDoc.close();65 66 } catch(Exception e) {67 e.printStackTrace();68 }69 }70 }转载
