How to disable auto resizing for a JTable in Java?
To disable auto resizing for a table in Java, set the setAutoResizeMode() to AUTO_RESIZE_OFF −
JTable table = new JTable(tableModel); table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
The following is an example to disable auto resizing for a JTable in Java −
package my;
import java.awt.Dimension;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JRootPane;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.table.DefaultTableModel;
public class SwingDemo {
public static void main(String[] argv) throws Exception {
JFrame frame = new JFrame("Demo");
JPanel panel = new JPanel();
String data[][] = { {"Australia","5","1"},
{"US","10","2"},
{"Canada","9","3"},
{"India","7","4"},
{"Poland","2","5"},
{"SriLanka","5","6"}
};
String col [] = {"Team","Selected Players","Rank"};
DefaultTableModel tableModel = new DefaultTableModel(data,col);
JTable table = new JTable(tableModel);
table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
Dimension dim = new Dimension(50,2);
table.setIntercellSpacing(new Dimension(dim));
JScrollPane scrollPane = new JScrollPane(table);
panel.add(scrollPane);
frame.add(panel);
frame.setSize(600,400);
frame.setUndecorated(true);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.getRootPane().setWindowDecorationStyle(JRootPane.INFORMATION_DIALOG);
frame.setVisible(true);
}
}The output is as follows. Now, the table won’t get auto-resized on its own and would appear like this −
Now, to display the table columns completely, you can drag the column header manually. After that, the entire table would be visible as shown below −
