help with printing a JTable

[L19htn1n9]

I need help printing a JTable, i used the .print() method, but when i do that, it prints a empty rectangle, this is my code right here:

package jtable;

import java.awt.Dimension;
import java.awt.FlowLayout;
import java.awt.print.PrinterException;
import java.text.MessageFormat;

import javax.swing.*;

public class table extends JFrame{

	/**
	 * @param args
	 */
	
	JTable table;
	public static void main(String[] args) {
		table gui = new table();
		gui.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		gui.setSize(600, 200);
		gui.setTitle("Table test");
		gui.setVisible(true);
		
	}
	
	public table(){
		setLayout( new FlowLayout() );
		
		String[] columnNames = {"Naam", "Achternaam", "Geboorte jaar"};
		
		Object[] [] data = {
				{"Freek", "van der Toorn", "1993"},
				{"Jesse", "Frerichs", "1993"}
		};
		
		table = new JTable(data, columnNames);
		table.setPreferredScrollableViewportSize(new Dimension(500, 50));
		table.setFillsViewportHeight(true);
		
		JScrollPane scrollPane = new JScrollPane(table);
		add(scrollPane);
		
		
		MessageFormat header = new MessageFormat("Page {0,number,integer}");
		try {
			table.print(JTable.PrintMode.FIT_WIDTH, header, null);
		} catch (PrinterException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}	
		
	}

}

it just shows the outlines of a rectangle, about half the width of a A4 piece of paper and at the top op the page in the center

Are you printing before the table has been displayed in the GUI?

[L19htn1n9]

it says so in the code, first i create the JTable, then i add its content, and then i add the JTable to the screen and lastly i try to print it

[Norm]

But it hasn't be set visible yet. Add code to do the print AFTER the GUI is visible.

Explicitly setting the table's size may also do it.

table.setSize(table.getPreferredSize());
