Set size of JTable in JScrollPane and in JPanel with the size of the JFrame
- by user1761818
I want the table with the same width as the frame and also when I resize the frame the table need to be resized too. I think setSize() of JTable doesn't work correctly. Can you help me?
import java.awt.Color;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.SwingUtilities;
public class Main extends JFrame {
public Main() {
setSize(400, 600);
String[] columnNames = {"A", "B", "C"};
Object[][] data = {
{"Moni", "adsad", 2},
{"Jhon", "ewrewr", 4},
{"Max", "zxczxc", 6}
};
JTable table = new JTable(data, columnNames);
JScrollPane tableSP = new JScrollPane(table);
int A = this.getWidth();
int B = this.getHeight();
table.setSize(A, B);
JPanel tablePanel = new JPanel();
tablePanel.add(tableSP);
tablePanel.setBackground(Color.red);
add(tablePanel);
setTitle("Marks");
setLocationRelativeTo(null);
setDefaultCloseOperation(EXIT_ON_CLOSE);
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
Main ex = new Main();
ex.setVisible(true);
}
});
}
}
