Appending a new row to a JTable at runtime

Question

I am developing a Java application that uses a JTable. I want to allow the user to enter data in a JTable that can later be printed or saved. The issues is: Suppose the user has entered some data and the cursor is on the last cell of the row in a table (I have uploaded an image-suppose the cursor is on the highlighted cell).How do I make it in such a way that when a user presses the Enter Button(Keyboard button) the application will add/append a new row that is empty to the table so that the user can fill in other data.

Try this...

  JTable table = new JTable();
  DefaultTableModel tblModel = new DefautlTableModel(0,0);

  table.setModel(tblModel);



  //an action or click then you should run this code


  tblModel.addRow(new Object[]{""});
