public class CellCreationExample {
    public static void main(String[] args) {
        // Step 1: Create a new PDF document
        Document document = new Document();
        
        try {
            // Step 2: Create a PdfWriter instance to write to a file
            PdfWriter.getInstance(document, new FileOutputStream("output.pdf"));
            
            // Step 3: Open the document
            document.open();
            
            // Step 4: Create a Table instance
            Table table = new Table(2); // Creating a table with 2 columns
            
            // Step 5: Create a parent cell
            Cell parentCell = new Cell("Parent Cell");
            
            // Step 6: Create a child cell
            Cell childCell = new Cell("Child Cell");
            
            // Step 7: Add the child cell to the parent cell
            parentCell.addElement(childCell);
            
            // Step 8: Add the parent cell to the table
            table.addCell(parentCell);
            
            // Step 9: Add the table to the document
            document.add(table);
            
            // Step 10: Close the document
            document.close();
            
            System.out.println("PDF created successfully!");
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
