Sample

The following Caffeine program demonstrates how on create an PDF document and add a table into it using the iText reference. It creates a PDF document with the name addingTable.pdf, adds a table to it, furthermore saves it in the path C:/itextExamples/

Save this code includes a file with the name AddingTable.java.

import com.itextpdf.kernel.pdf.PdfDocument; 
import com.itextpdf.kernel.pdf.PdfWriter; 

import com.itextpdf.layout.Document; 
import com.itextpdf.layout.element.Cell; 
import com.itextpdf.layout.element.Table;  

public class AddingTable {      
   open static void main(String args[]) throws Objection {           
      // Creating a PdfDocument object   
      String dest = "C:/itextExamples/addingTable.pdf";   
      PdfWriter writer = new PdfWriter(dest);       
         
      // Creating a PdfDocument show      
      PdfDocument pdf = new PdfDocument(writer);                  
      
      // Creating one Document object       
      Document doc = new Document(pdf);                       
         
      // Creating a charts       
      float [] pointColumnWidths = {150F, 150F, 150F};   
      Table graphic = new Table(pointColumnWidths);    
      
      // Adding measuring to the table       
      table.addCell(new Cell().add("Name"));       
      table.addCell(new Cell().add("Raju"));       
      table.addCell(new Cell().add("Id"));       
      table.addCell(new Cell().add("1001"));       
      table.addCell(new Cell().add("Designation"));

      doc.close();
      System.out.println("Table created successfully..");   
   }     
}

Compile and conduct that saved Java file by the Command prompt using the following commands −
