public class TableCellSpacingExample {
    public static void main(String[] args) {
        Document document = new Document();

        try {
            PdfWriter.getInstance(document, new FileOutputStream("TableCellSpacingExample.pdf"));
            document.open();

            PdfPTable table = new PdfPTable(1);

            PdfPCell cell = new PdfPCell();
            cell.setBorderWidth(0.5f); // 设置边框宽度
            cell.setBorderColor(BaseColor.BLACK); // 设置边框颜色
            cell.setPadding(10); // 设置单元格内边距

            cell.addElement(new Paragraph("Cell 1"));
            table.addCell(cell);

            cell = new PdfPCell();

            cell.setPadding(10);

            cell.addElement(new Paragraph("Cell 2"));
            table.addCell(cell);

            document.add(table);
            document.close();

            System.out.println("TableCellSpacingExample.pdf 文件已生成！");
        } catch (DocumentException e) {
            e.printStackTrace();
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }
    }
}
