Java Program to append a row to a JTable in Java Swing
To append a row, you can use the addRow() method. Ley us first create a table wherein we need to append a row −
DefaultTableModel tableModel = new DefaultTableModel(); JTable table = new JTable(tableModel);
Add some columns to the table −
tableModel.addColumn("Language/ Technology");
tableModel.addColumn("Difficulty Level");Add some rows −
tableModel.insertRow(0, new Object[] { "CSS", "Easy" });
tableModel.insertRow(0, new Object[] { "HTML5", "Easy"});
tableModel.insertRow(0, new Object[] { "JavaScript", "Intermediate" });
tableModel.insertRow(0, new Object[] { "jQuery", "Intermediate" });
tableModel.insertRow(0, new Object[] { "AngularJS", "Difficult"});Now, if you need to append a row to the table we created above, use the addrow() method −
tableModel.addRow(new Object[] { "WordPress", "Easy" });The following is an example to append a row to a JTable −
Example
package my;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.table.DefaultTableModel;
public class SwingDemo {
public static void main(String[] argv) throws Exception {
DefaultTableModel tableModel = new DefaultTableModel();
JTable table = new JTable(tableModel);
tableModel.addColumn("Language/ Technology");
tableModel.addColumn("Difficulty Level");
tableModel.insertRow(0, new Object[] { "CSS", "Easy" });
tableModel.insertRow(0, new Object[] { "HTML5", "Easy"});
tableModel.insertRow(0, new Object[] { "JavaScript", "Intermediate" });
tableModel.insertRow(0, new Object[] { "jQuery", "Intermediate" });
tableModel.insertRow(0, new Object[] { "AngularJS", "Difficult"});
// adding a new row
tableModel.insertRow(tableModel.getRowCount(), new Object[] { "ExpressJS", "Intermediate" });
// appending a new row
tableModel.addRow(new Object[] { "WordPress", "Easy" });
JFrame f = new JFrame();
f.setSize(550, 350);
f.add(new JScrollPane(table));
f.setVisible(true);
}
}Output
