We can add nested tables to a PDF by installing the document class. Following are the steps to format the text in a PDF using java.
1. Create a PDF writer object
The PdfWriter class here represents the DocWriter for a PDF. This class belongs to the package com.itextpdf.kernel.pdf. The constructor of this class accepts a string, representing the trail of the file where the PDF is to be created.
Create the PdfWriter class by passing a string value (representing the trail where you would like to make a PDF) to its constructor.
2. Create a PDFdocument object
The PdfDocument class is the class that represents the PDF Document in iText. This class belongs to the package com.itextpdf.kernel.pdf. To create this class (in writing mode), you would like to pass an object of the category PdfWriter to its constructor.
Create the PdfDocument class by passing the above created PdfWriter object to its constructor.
