Moving row in Jtable

Question

Hi,
what i want is to move row UP and DOWN. I have my own Abstract table model. Im looking for the easyest way to do this.
public void moveRow(int i, int j){
    Vector v = new Vector();
    v = (Vector)data.get(j);
    data.add(j, data.get(i));
    data.add(i, v);
    fireTableRowsUpdated(i,j);
  }

Answer 1

The following example moves the selected row of a table up or down
    m_table - your JTable
    m_model - your DefaultTableModel
    m_btnUp, m_btnDown  - your up/down buttons
    m_btnUp    .addActionListener(new MoveUpAction());
    m_btnDown  .addActionListener(new MoveDownAction());
    class MoveUpAction implements ActionListener
        public void actionPerformed(ActionEvent e)
            int row = m_table.getSelectedRow();
            if (row == -1) return;
            if (row ==  0) return;
            m_model.moveRow(row,row,row-1);
            m_table.setRowSelectionInterval(row-1, row-1);
    class MoveDownAction implements ActionListener
        public void actionPerformed(ActionEvent e)
            int row = m_table.getSelectedRow();
            if (row == -1) return;
            if (row ==  m_table.getRowCount()-1) return;
            m_model.moveRow(row,row,row+1);
            m_table.setRowSelectionInterval(row+1, row+1);
    it will be wise to set the table to have single selection:
         m_table.getSelectionModel().setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
