pdf tables

In this program we are going to tell you how we can make a table in a pdf file irrespective of the fact whether it exists or not. If it exists then its fine, otherwise a pdf file will be created. 

To make a program over this, firstly we need to import some packages. Remember to make this program the first and foremost thing to remember is to place the iText.jar in WEB-INF/lib of your web application. The packages we were talking about are java.io.* for input output, com.lowagie.text.pdf.*, and com.lowagie.text.*. These two package will help us to make and use pdf file in our program.

Now create a file named tablePDF. Remember the name of the file should be such that the reader can understand what the program is going to perform. Inside the class declare a main method inside which we are going to write the logic of our program.

Firstly make a object of class Document. The Document describes a document's page size, margins, and other important attributes. It works as a container for a document's chapters, sections, images, paragraphs, and other content. 

Now create a document writer that writes the equivalent syntax for a document's content to a specific OutputStream. PdfWriter.getInstance() creates a PDF document writer that writes PDF syntax to concerned file by a FileOutputStream. If the pdf file doesn't exist then it will create a pdf file by that name.

Now open the document by document.open(). Make a object of PdfPTable class. It will create a table with 2 rows and 2 columns as we have passed 2 inside the constructor of a PdfPTable. After that add the content to the table. Now add the table to the Document object. At last closes the document by using the document.close(). The closing of the document is important because it flushes and closes the OutputStream instance. 

The code of the program is given below:

import java.io.*;
import com.lowagie.text.*;
import com.lowagie.text.pdf.*;

public class tablePDF{
    public static void main(String arg[])throws Exception{
       Document document=new Document();
       PdfWriter.getInstance(document,new FileOutputStream("tablePDF.pdf"));
       document.open();
       PdfPTable table=new PdfPTable(2);
       table.addCell("Name");
       table.addCell("Place");
       table.addCell("RoseIndia");
       table.addCell("Delhi");
       document.add(table);
       document.close()
   }
}

The output of the program is given below:
