Hi everyone,

I am currently trying to print a multipage JTable but the the thing is on the left hand side of the JTable does not have any grid lines and i have tried to draw a rectangle around the jTable before printing it but nothing is happening.

Another thing is that when the JTable goes on the next page for printing there are trailing grid lines on the previous page. I have tried clipping and translating it but nothing works.

You guys can try removing the painting of the Table Headers to get a clearer picture if you want

Here is the code with a mini test program so you guys can run the program and see what i mean

Code:
import java.awt.*;
import java.awt.image.*;
import java.io.*;
import java.util.*;
import java.awt.print.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.event.*;
import javax.swing.table.*;
import javax.imageio.*;

public class JTables2 implements ActionListener

{

	JFrame fr = new JFrame ("Frame");

	JButton Button12 = new JButton("Print");

	DefaultTableModel TableModel1 = new DefaultTableModel(20, 30);

	//The below command line sets the table model to the JTable

	JTable Table1 = new JTable(TableModel1);

	JScrollPane ScrollPane1 = new JScrollPane(Table1, ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS, 
	ScrollPaneConstants.HORIZONTAL_SCROLLBAR_ALWAYS);  

	Dimension Size1 = new Dimension();

	PrinterJob prnJob;
	PageFormat format;

	public void initialize ()
	{ 
		Container pane = fr.getContentPane();
		pane.setLayout(new FlowLayout());
		fr.setSize(250,300);
		fr.setLocation(300,300);
		fr.setBackground(Color.lightGray);
		//The below command line must be set to false so that user 
		//resizing is allowed

		Table1.setAutoCreateColumnsFromModel(false);
		Size1.width = 350;
		Size1.height = 250;
		ScrollPane1.setPreferredSize(Size1);
		Table1.setModel(TableModel1);
		Table1.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
		Table1.setAutoResizeMode(JTable.AUTO_RESIZE_OFF); 

		pane.add(ScrollPane1);
		pane.add(Button12);

		fr.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		Button12.addActionListener(this);
		fr.pack();
		fr.setVisible(true);
	}


	public void printData () 
	{
		//This function prints the contents of the JTable

		StyledTextTableRenderer2 StyledTextTableRenderer1 = new StyledTextTableRenderer2();
		StyledTextTableRenderer1.settable(Table1);

		try 
		{
			//The below command line gets the printer job

			prnJob = PrinterJob.getPrinterJob();

			if(format == null)
			{
				format = prnJob.defaultPage();

			//The below command line sets the printable interface and the
			//format for the page to be printed

			prnJob.setPrintable(StyledTextTableRenderer1, format);

		/*

		return Printable.PAGE_EXISTS;
	}

	public void settable(JTable table)
	{
		//This function gets the JTable and its table model

		Table1 = table;
		Table1.setShowGrid(false);
	}

}
Basically i am trying to print a JTable with the option of table headers as a complete grid and withou any trainling lines

I know that 1.5 now has printing but i need to use this way of printing(i.e. by using the printable interface) for the program to suit a special kind of need

Any help is greatly appreciated

Thank You

Yous Sincerely

Richard West
