Itext: set headers to table

It is always good practice to set headers to tables. PdfPTable class provides setHeaderRows method to set given number of rows as headers to a table.

public void setHeaderRows(int headerRows)

Following is the working application.

import java.io.FileOutputStream;
import java.io.IOException;
import java.net.MalformedURLException;

import com.itextpdf.text.Document;
import com.itextpdf.text.DocumentException;
import com.itextpdf.text.Phrase;
import com.itextpdf.text.pdf.PdfPCell;
import com.itextpdf.text.pdf.PdfPTable;
import com.itextpdf.text.pdf.PdfWriter;

public class TestTable {
 private static final String fileName = "/Users/harikrishna_gurram/Documents/itext/tableEx.pdf";

 public static void main(String args[]) throws DocumentException, MalformedURLException, IOException {

  Document document = new Document();
  PdfWriter.getInstance(document, new FileOutputStream(fileName));
  document.open();

  PdfPTable table = new PdfPTable(2);
  table.setHeaderRows(1);
  PdfPCell cell = new PdfPCell();

  cell.setPhrase(new Phrase("Number"));
  table.addCell(cell);

  cell.setPhrase(new Phrase("Square"));
  table.addCell(cell);

  for (int i = 1; i < 100; i++) {
   cell.setPhrase(new Phrase(Integer.toString(i)));
   table.addCell(cell);

   cell.setPhrase(new Phrase(Integer.toString(i * i)));
   table.addCell(cell);
  }
  document.add(table);

  document.close();
 }
}
