public class BackgroundToTable {
   public static void main(String args[]) throws Exception {

     //Creating a PdfWriter object
      String dest = "C:/itextExamples/addingBackground.pdf";
      PdfWriter writer = new PdfWriter(dest);

     //Creating a PdfDocument object
      PdfDocument pdfDoc = new PdfDocument(writer);

     //Creating a Document object
      Document doc = new Document(pdfDoc);

     //Creating a table
      float [] pointColumnWidths = {200F, 200F};
      Table table = new Table(pointColumnWidths);

     //Populating row 1 and adding it to the table
      Cell c1 = new Cell();                       //Creating cell1

      c1.add("Name");                             //Adding name to cell1
      c1.setBackgroundColor(Color.DARK_GRAY);     //Setting background color
      c1.setBorder(Border.NO_BORDER);             //Setting border
      c1.setTextAlignment(TextAlignment.CENTER);  //Setting text alignment
      table.addCell(c1);                          //Adding cell1 to the table

      Cell c2 = new Cell();
      c2.add("Raju");
      c2.setBackgroundColor(Color.GRAY);
      c2.setBorder(Border.NO_BORDER);
      c2.setTextAlignment(TextAlignment.CENTER);
      table.addCell(c2);

     //Populating row 2 and adding it to the table
      Cell c3 = new Cell();

      c3.add("Id");
      c3.setBackgroundColor(Color.WHITE);
      c3.setBorder(Border.NO_BORDER);
      c3.setTextAlignment(TextAlignment.CENTER);
      table.addCell(c3);

      Cell c4 = new Cell();
      c4.add("001");
      c4.setBackgroundColor(Color.WHITE);
      c4.setBorder(Border.NO_BORDER);
      c4.setTextAlignment(TextAlignment.CENTER);
      table.addCell(c4);

     //Populating row 3 and adding it to the table
      Cell c5 = new Cell();

      c5.add("Designation");
      c5.setBackgroundColor(Color.DARK_GRAY);
      c5.setBorder(Border.NO_BORDER);
      c5.setTextAlignment(TextAlignment.CENTER);
      table.addCell(c5);

      Cell c6 = new Cell();
      c6.add("Programmer");
      c6.setBackgroundColor(Color.GRAY);
      c6.setBorder(Border.NO_BORDER);
      c6.setTextAlignment(TextAlignment.CENTER);
      table.addCell(c6);

     //Adding Table to document
      doc.add(table);

     //Closing the document
      doc.close();
      System.out.println("Background added successfully..");
   }
}
