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

The width of a table column defined relatively between each column. On the following example we define an array floats that stores the column widths. We define the second column twice as big 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.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;


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

            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};

        } catch (DocumentException | FileNotFoundException e) {
        } finally {
