How can we disable the cell editing inside a JTable in Java?
A JTable is a subclass of JComponent for displaying complex data structures. A JTable can follow the Model View Controller (MVC) design pattern for displaying the data in rows and columns. A JTable can fire TableModelListener, TableColumnModelListener, ListSelectionListener, CellEditorListener and RowSorterListener interfaces. By default, we can edit the text and modify it inside a JTable cell. We can also disable the cell editing inside a table by calling the editCellAt() method of JTable class and it must return false.
Example
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.table.*;
public final class DisableJTableMouseClickTest extends JFrame {
private JTable table;
private JScrollPane scrollPane;
public DisableJTableMouseClickTest() {
setTitle("DisableJTableMouseClick Test");
String[] columnNames = {"Country", "Rank"};
Object[][] data = {{"England", "1"}, {"India", "2"}, {"New Zealand", "3"}, {"Australia", "4"}, {"South Africa","5"}, {"Pakistan","6"}};
table = new JTable(data, columnNames) {
public boolean editCellAt(int row, int column, java.util.EventObject e) {
return false;
}
};
table.setRowSelectionAllowed(false);
scrollPane= new JScrollPane(table);
add(scrollPane);
setSize(400, 275);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setLocationRelativeTo(null);
setVisible(true);
}
public static void main(String[] args) {
new DisableJTableMouseClickTest();
}
}Output
