How to export a complete JTable component in pdf at a specific coordinate

Question

In my project I have to print JTable components in a pdf with all the customizations(like borders,colors etc). For this requirement I searched a little bit and found one code to print JTable in pdfs. But after printing I found that table's border for 1st row and 1st columns are missing plus I didn't find a way to print at some specific coordinate. Please look at the specific code below:-

package com.jpmorgan.dqreport;

import java.awt.BorderLayout;
import java.awt.Graphics2D;
import java.awt.Shape;
import java.io.FileOutputStream;

import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JTable;

import com.lowagie.text.Document;
import com.lowagie.text.PageSize;
import com.lowagie.text.pdf.PdfContentByte;
import com.lowagie.text.pdf.PdfWriter;

public class JTable2Pdf extends JFrame {
  private JTable table;

  public JTable2Pdf() {
    getContentPane().setLayout(new BorderLayout());
    createTable();
  }
  private void createTable() {
      Object[][] data = {
                {"Kathy", "Smith",
                 "SnowboardingXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX", new Integer(5), new Boolean(false)},
                {"John", "Doe",
                 "Rowing", new Integer(3), new Boolean(true)},
                {"Sue", "Black",
                 "Knitting", new Integer(2), new Boolean(false)},
                {"Jane", "White",
                 "Speed reading", new Integer(20), new Boolean(true)},
                {"Joe", "Brown",
                 "Pool", new Integer(10), new Boolean(false)}
                };
      String[] columnNames = {"First Name",
              "Last Name",
              "Sport",
              "# of Years",
              "Vegetarian"};

    table = new JTable(data, columnNames);

    JPanel tPanel = new JPanel(new BorderLayout());
    tPanel.add(table.getTableHeader(), BorderLayout.NORTH);
    tPanel.add(table, BorderLayout.CENTER);

    getContentPane().add(tPanel, BorderLayout.CENTER);
  }
  private void print() {
    Document document = new Document(PageSize.A4.rotate());
    try {
      PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream("C:\\jTable.pdf"));

      document.open();
      PdfContentByte cb = writer.getDirectContent();

      cb.saveState();
      Graphics2D g2 = cb.createGraphics(500, 500);

      Shape oldClip = g2.getClip();
      g2.clipRect(10, 0, 500, 500);

      table.print(g2);
      g2.setClip(oldClip);

      g2.dispose();
      cb.restoreState();
    } catch (Exception e) {
      System.err.println(e.getMessage());
    }
    document.close();
  }
  public static void main(String[] args) {
    JTable2Pdf frame = new JTable2Pdf();
    frame.pack();
    frame.setVisible(true);
    frame.print();
  }
}

Please suggest someway to print the entire JTable at a specific coordinate.

Thanks

Answer 1

A JTable is notoriously difficult to get rendered correctly for images (or I guess, printing). See this thread on which some of the gurus weigh in with tips.

Looking closely at the screenshots of that thread suggests that the default Metal table has no border on the far left.

The table in Nimbus PLAF does, though.

Hi I resolved the code by adding like below:-

cb.saveState();

PdfTemplate pdfTemplate = cb.createTemplate(table.getWidth(), table.getHeight());
Graphics2D g2 = pdfTemplate.createGraphics(table.getWidth(), table.getHeight());
/*g2.setColor(Color.BLACK);
g2.drawRect(x-2, y-2, table.getWidth()+2, table.getHeight()+2);*/
table.print(g2);
System.out.println("x="+x + "," + "y=" + y);
cb.addTemplate(pdfTemplate, x, y);
g2.dispose();
cb.restoreState();
