How to add a new row to JTable with insertRow() in Java Swing
Let us first create a table with DefaulTabelMode −
DefaultTableModel tableModel = new DefaultTableModel(); JTable table = new JTable(tableModel);
Now, add a column to the table −
tableModel.addColumn("Languages");The insertRow() method will now add a row −
tableModel.insertRow(0, new Object[] { "CSS" });
tableModel.insertRow(0, new Object[] { "HTML5" });
tableModel.insertRow(0, new Object[] { "JavaScript" });
tableModel.insertRow(0, new Object[] { "jQuery" });The following is an example to add a new row to 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("Languages");
tableModel.insertRow(0, new Object[] { "CSS" });
tableModel.insertRow(0, new Object[] { "HTML5" });
tableModel.insertRow(0, new Object[] { "JavaScript" });
tableModel.insertRow(0, new Object[] { "jQuery" });
tableModel.insertRow(0, new Object[] { "AngularJS" });
// adding a new row
tableModel.insertRow(tableModel.getRowCount(), new Object[] { "ExpressJS" });
JFrame f = new JFrame();
f.setSize(550, 350);
f.add(new JScrollPane(table));
f.setVisible(true);
}
}This will produce the following output −
