How do I create nested Table in iText?

By Wayan in iText PDF 0 Comment

This example show you how to create nested table in iText. To create a nested table you can add a com.itextpdf.text.pdf.PdfPTable object into a cell using the com.itextpdf.text.pdf.PdfPCell‘s addElement() method.

package org.kodejava.example.itextpdf;

import com.itextpdf.text.Document;
import com.itextpdf.text.DocumentException;
import com.itextpdf.text.Phrase;
import com.itextpdf.text.pdf.PdfPCell;
import com.itextpdf.text.pdf.PdfPTable;
import com.itextpdf.text.pdf.PdfWriter;

import java.io.FileNotFoundException;
import java.io.FileOutputStream;

public class TableNestedDemo {
    public static void main(String[] args) {
        Document doc = new Document();
        try {
            PdfWriter.getInstance(doc, new FileOutputStream("TableNestedDemo.pdf"));
            doc.open();

            PdfPTable table = new PdfPTable(3);
            PdfPCell cell1 = new PdfPCell(new Phrase("Cell 1"));
            PdfPCell cell2 = new PdfPCell(new Phrase("Cell 2"));
            PdfPCell cell3 = new PdfPCell(new Phrase("Cell 3"));

            PdfPTable nestedTable = new PdfPTable(2);
            nestedTable.addCell(new PdfPCell(new Phrase("Nested 1")));
            nestedTable.addCell(new PdfPCell(new Phrase("Nested 2")));
            cell3.addElement(nestedTable);

            table.addCell(cell1);
            table.addCell(cell2);
            table.addCell(cell3);
            doc.add(table);
        } catch (DocumentException | FileNotFoundException e) {
            e.printStackTrace();
        } finally {
            doc.close();
        }
    }
}

How do I set Table’s cell alignment in iText?

By Wayan in iText PDF 0 Comment

We can set table cell’s content alignment horizontally and vertically. To set the horizontal alignment we use the setHorizontalAlignment() method. To align it vertically we use the setVerticalAlignment() method. The alignment constant is defined in the com.itextpdf.text.Element class.

package org.kodejava.example.itextpdf;

import com.itextpdf.text.Document;
import com.itextpdf.text.DocumentException;
import com.itextpdf.text.Element;
import com.itextpdf.text.Phrase;
import com.itextpdf.text.pdf.PdfPCell;
import com.itextpdf.text.pdf.PdfPTable;
import com.itextpdf.text.pdf.PdfWriter;

import java.io.FileNotFoundException;
import java.io.FileOutputStream;

public class TableCellAlignment {
    public static void main(String[] args) {
        Document doc = new Document();
        try {
            PdfWriter.getInstance(doc, new FileOutputStream("TableCellAlignment.pdf"));
            doc.open();

            // Setting table's cells horizontal alignment
            PdfPTable table = new PdfPTable(3);
            PdfPCell cell1 = new PdfPCell(new Phrase("Cell 1"));
            cell1.setHorizontalAlignment(Element.ALIGN_LEFT);
            table.addCell(cell1);
            PdfPCell cell2 = new PdfPCell(new Phrase("Cell 2"));
            cell2.setHorizontalAlignment(Element.ALIGN_CENTER);
            table.addCell(cell2);
            PdfPCell cell3 = new PdfPCell(new Phrase("Cell 3"));
            cell3.setHorizontalAlignment(Element.ALIGN_RIGHT);
            table.addCell(cell3);
            table.completeRow();

            // Setting table's cells vertical alignment
            PdfPCell[] cells = new PdfPCell[3];
            int[] alignments = new int[]{
                    Element.ALIGN_TOP,
                    Element.ALIGN_MIDDLE,
                    Element.ALIGN_BOTTOM
            };
            for (int i = 0; i < cells.length; i++) {
                cells[i] = new PdfPCell(new Phrase("Cell " + (i + 1)));
                cells[i].setMinimumHeight(50);
                cells[i].setVerticalAlignment(alignments[i]);
                table.addCell(cells[i]);
            }
            table.completeRow();

            doc.add(table);
        } catch (DocumentException | FileNotFoundException e) {
            e.printStackTrace();
        } finally {
            doc.close();
        }
    }
}

How do I set Table’s cell padding in iText?

By Wayan in iText PDF 0 Comment

You can set the cell’s padding using the com.itextpdf.text.pdf.PdfPCell‘s setPadding() method. To set the padding individually you can use the setPaddingTop(), setPaddingRight(), setPaddingBottom(), and setPaddingLeft() methods to set the top, right, bottom and left padding respectively.

package org.kodejava.example.itextpdf;

import com.itextpdf.text.Document;
import com.itextpdf.text.DocumentException;
import com.itextpdf.text.Phrase;
import com.itextpdf.text.pdf.PdfPCell;
import com.itextpdf.text.pdf.PdfPTable;
import com.itextpdf.text.pdf.PdfWriter;

import java.io.FileNotFoundException;
import java.io.FileOutputStream;

public class TableCellPadding {
    public static void main(String[] args) {
        Document doc = new Document();
        try {
            PdfWriter.getInstance(doc, new FileOutputStream("TableCellPadding.pdf"));
            doc.open();

            int numColumns = 3;
            PdfPTable table = new PdfPTable(numColumns);
            PdfPCell[] cells = new PdfPCell[numColumns];
            for (int i = 0; i < numColumns; i++) {
                cells[i] = new PdfPCell(new Phrase("Cell " + i + 1));
                // Set cell's padding equally for all side of the
                // cell.
                cells[i].setPadding(10);
                table.addCell(cells[i]);
            }
            table.completeRow();

            cells = new PdfPCell[numColumns];
            for (int i = 0; i < numColumns; i++) {
                cells[i] = new PdfPCell(new Phrase("Cell " + i + 1));
                // Set cell's padding individually for top, right,
                // bottom and left padding.
                cells[i].setPaddingTop(20);
                cells[i].setPaddingRight(30);
                cells[i].setPaddingBottom(20);
                cells[i].setPaddingLeft(30);
                table.addCell(cells[i]);
            }
            table.completeRow();
            doc.add(table);
        } catch (DocumentException | FileNotFoundException e) {
            e.printStackTrace();
        } finally {
            doc.close();
        }
    }
}
