Add nested table in PDF using iText

In our previous post we had seen how simple tables are added in PDF using PdfPTable. PdfPTable can be used inside Cell of simple table to create separate table creating nested tables. Lets see how to add nested table in PDF using iText.
The individual cell of the table can be treated as space for creating new tables. This way we can create various chains of nested table.

Example

package com.kscodes.examples.itext;

import java.io.FileOutputStream;

import com.itextpdf.text.Document;
import com.itextpdf.text.pdf.PdfPTable;
import com.itextpdf.text.pdf.PdfWriter;

public class NestedTableExample {

	public static void main(String args[]) {

		// Create a Document object
		Document document = new Document();

		try {
			// Create a PdfWriter instance and use the document to write the pdf
			// to a specified location
			PdfWriter.getInstance(document, new FileOutputStream("K:\\Kscodes\\pdf\\itext-nested-tables.pdf"));

			// open the document
			document.open();

			// Create a Simple table
			PdfPTable table = new PdfPTable(4);

			// Set First row as header
			table.setHeaderRows(1);
			// Add header details
			table.addCell("Name");
			table.addCell("Class");
			table.addCell("Subjects");
			table.addCell("Result");

			// Add the data
			table.addCell("Student1");
			table.addCell("5th");

			// Create a new Table
			PdfPTable childTable1 = new PdfPTable(2);
			childTable1.addCell("Maths");
			childTable1.addCell("B");
			childTable1.addCell("History");
			childTable1.addCell("A");

			// Add the new table to the Cell of parent table
			table.addCell(childTable1);
			table.addCell("Pass");

			// Add more data
			table.addCell("Student 2");
			table.addCell("6th");
			PdfPTable childTable2 = new PdfPTable(2);
			childTable2.addCell("Maths");
			childTable2.addCell("C-");
			childTable2.addCell("History");
			childTable2.addCell("F");

			table.addCell(childTable2);
			table.addCell("Fail");

			document.add(table);

			// close the document
			document.close();

			System.out.println("PDF created at the location !!!");
		} catch (Exception e) {
			System.out.println("Exception occured :: " + e);
		}
	}
}

package com.kscodes.examples.itext;

childTable1.addCell("Maths");

childTable1.addCell("B");

childTable1.addCell("History");

childTable1.addCell("A");

// Add the new table to the Cell of parent table

table.addCell(childTable1);

table.addCell("Pass");

// Add more data

table.addCell("Student 2");

table.addCell("6th");

PdfPTable childTable2 = new PdfPTable(2);

childTable2.addCell("Maths");

childTable2.addCell("C-");

childTable2.addCell("History");

childTable2.addCell("F");

table.addCell(childTable2);

table.addCell("Fail");

document.add(table);

// close the document

document.close();

System.out.println("PDF created at the location !!!");

} catch (Exception e) {

System.out.println("Exception occured :: " + e);

}
