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 Saryada in iText PDF Last modified: February 7, 2017 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 Saryada in iText PDF Last modified: February 6, 2017 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();
        }
    }
}

How do I create Table cell that span multiple columns in iText?

By Wayan Saryada in iText PDF Last modified: February 6, 2017 0 Comment

To create a cell in a table that span into multiple columns you can use the setColspan() method in the com.itextpdf.text.pdf.PdfPCell object. The example below show you how to do it.

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

            // Creates a table with four column. The first rows
            // will have cell 1 to cell 4.
            PdfPTable table = new PdfPTable(4);
            table.addCell(new PdfPCell(new Phrase("Cell 1")));
            table.addCell(new PdfPCell(new Phrase("Cell 2")));
            table.addCell(new PdfPCell(new Phrase("Cell 3")));
            table.addCell(new PdfPCell(new Phrase("Cell 4")));
            table.completeRow();

            // Creates another row that only have to columns.
            // The cell 5 and cell 6 width will span two columns
            // in width.
            PdfPCell cell5 = new PdfPCell(new Phrase("Cell 5"));
            cell5.setColspan(2);
            PdfPCell cell6 = new PdfPCell(new Phrase("Cell 6"));
            cell6.setColspan(2);
            table.addCell(cell5);
            table.addCell(cell6);
            table.completeRow();

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

How do I set column width of a Table in iText?

By Wayan Saryada in iText PDF Last modified: February 6, 2017 2 Comments

The width of a table column defined relatively between each columns. On the following example we define an array floats that stores the column widths. We define the second column twice as bigger as the first column and the third column is three times bigger than the first column.

To set the width we call the table‘s setWidths() method. This method can accept an array of floats or an array of integers. Here is an example code:

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

            PdfPTable table = new PdfPTable(4);
            table.addCell(new PdfPCell(new Phrase("Cell 1")));
            table.addCell(new PdfPCell(new Phrase("Cell 2")));
            table.addCell(new PdfPCell(new Phrase("Cell 3")));
            table.addCell(new PdfPCell(new Phrase("Cell 4")));

            // Defiles the relative width of the columns
            float[] columnWidths = new float[]{10f, 20f, 30f, 10f};
            table.setWidths(columnWidths);

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