Do you know how I can add a new row to a jTable?
741
To add a row: DefaultTableModel model = (DefaultTableModel) table. getModel(); model. addRow(new Object[]{"Column 1", "Column 2", "Column 3"});
Right-click the table and select "Properties." The table's properties display, including the columns. You click a column and change the heading to edit the current columns. To add a new column, click "New" and type a heading for the column.
To add the data entered in the JTextFields you will need to register an ActionListener to your add button, in this case jButton1 . To add entries to your table model you could use a mutable model such as DefaultTableModel : DefaultTableModel model = new DefaultTableModel(data, columns);
The TableModel behind the JTable handles all of the data behind the table. In order to add and remove rows from a table, you need to use a DefaultTableModel
To create the table with this model:
JTable table = new JTable(new DefaultTableModel(new Object[]{"Column1", "Column2"})); To add a row:
DefaultTableModel model = (DefaultTableModel) table.getModel(); model.addRow(new Object[]{"Column 1", "Column 2", "Column 3"}); You can also remove rows with this method.
Full details on the DefaultTableModel can be found here
