itext Tables: iText 5 versus iText 7 HelloWorldTable.java (iText 5)

Example

In this example, we'll create the following table using iText 5:

We need the PdfPTable and PdfPCell class to achieve this:

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);
    PdfPCell cell = new PdfPCell(new Phrase("Cell with colspan 3"));
    cell.setColspan(3);
    cell.setHorizontalAlignment(Element.ALIGN_CENTER);
    table.addCell(cell);
    cell = new PdfPCell(new Phrase("Cell with rowspan 2"));
    cell.setRowspan(2);
    cell.setVerticalAlignment(Element.ALIGN_MIDDLE);
    table.addCell(cell);
    table.addCell("Cell 1.1");
    cell = new PdfPCell();
    cell.addElement(new Phrase("Cell 1.2"));
    table.addCell(cell);
    cell = new PdfPCell(new Phrase("Cell 2.1"));
    cell.setPadding(5);
    cell.setUseAscender(true);
    cell.setUseDescender(true);
    cell.setHorizontalAlignment(Element.ALIGN_CENTER);
    table.addCell(cell);
    cell = new PdfPCell();
    cell.setPadding(5);
    cell.setUseAscender(true);
    cell.setUseDescender(true);
    Paragraph p = new Paragraph("Cell 2.2");
    p.setAlignment(Element.ALIGN_CENTER);
    cell.addElement(p);
    table.addCell(cell);
    document.add(table);
    document.close();
}
