1.pom.xml導入使用的jar包
<dependency>
<groupId>com.itextpdf</groupId>
<artifactId>itext-pdfa</artifactId>
<version>5.5.0</version>
</dependency>
<dependency>
<groupId>com.itextpdf</groupId>

2.直接上代碼（數據導出為pdf文件，數據呈現樣式為自定義excel表格樣式，支持多頁展示）
public class DataToPdf { public static final String DEST = "pdf/tables.pdf"; public static void main(String[] args) throws IOException, DocumentException { File file = new File(DEST); file.getParentFile().mkdirs(); new DataToPdf().dataToPdf(DEST); } /** * 數據轉pdf * @param dest * @throws IOException * @throws DocumentException */ public void dataToPdf(String dest) throws IOException, DocumentException { Document document = new Document(); PdfWriter.getInstance(document, new FileOutputStream(dest)); document.open(); // 使用語言包字體 BaseFont abf = BaseFont.createFont("STSong-Light", "UniGB-UCS2-H",BaseFont.NOT_EMBEDDED); //字體 Font font = new Font(abf, 8); //段落 Paragraph p = new Paragraph("測試結算單", new Font(abf, 12, Font.BOLD)); p.setAlignment(Paragraph.ALIGN_CENTER); document.add(p); //表格 PdfPTable table = new PdfPTable(8);//numcolumns:列數 table.setSpacingBefore(16f);//表格與上面段落的空隙 //表格列創建並賦值 PdfPCell cell = new PdfPCell(new Phrase("單位名稱：測試有限公司", font));

cell.setHorizontalAlignment(Element.ALIGN_LEFT); cell.disableBorderSide(14); cell.setColspan(4); table.addCell(cell); table.setSpacingBefore(16f); document.add(table); document.close(); } }
3.上述代碼中對於IText字體設置可改：
使用iText中的字體 例：BaseFont.createFont("STSong-Light", "UniGB-UCS2-H",BaseFont.NOT_EMBEDDED); 使用Windows系統自帶的字體 例：BaseFont.createFont("C:/WINDOWS/Fonts/SIMYOU.TTF", BaseFont.IDENTITY_H,BaseFont.NOT_EMBEDDED); 使用外部引入的資源字體( 例：BaseFont.createFont("/SIMYOU.TTF", BaseFont.IDENTITY_H,BaseFont.NOT_EMBEDDED);
4.上述代碼生成的表格邊框隱藏方式：
1：代表上邊框 2：代表下邊框 4：代表左邊框 8：代表右邊框 //需要隱藏那些邊框就把對應的值加起來，得到的和就是要設置的值 //比如要隱藏左右邊框 就是 4+8=12 cell.disableBorderSide(12);//左右沒了
具體例子：
//隱藏上邊框 cell.disableBorderSide(1);
//隱藏下邊框 cell.disableBorderSide(2); //隱藏上、下邊框 cell.disableBorderSide(3); //隱藏左邊框 cell.disableBorderSide(4); //隱藏左、上邊框 cell.disableBorderSide(5); //隱藏左、下邊框 cell.disableBorderSide(6); //隱藏左、上、下邊框 cell.disableBorderSide(7); //隱藏右邊框 cell.disableBorderSide(8); //隱藏右、上邊框 cell.disableBorderSide(9); //隱藏右、下邊框 cell.disableBorderSide(10); //隱藏右、上、下邊框 cell.disableBorderSide(11); //隱藏左、右邊框 cell.disableBorderSide(12);//左右沒了 //隱藏上、左、右邊框 cell.disableBorderSide(13);//只剩下 //隱藏下、左、右邊框 cell.disableBorderSide(14);//只剩上 //隱藏全部 cell.disableBorderSide(15);//全沒了
5.運行展示效果
