jtable更新数据

  static JTable table;

    public void refrushTableData() {

        String[] columnNames = { "1000", "2000", "3000" };
        String[][] tableData = { { "1000", "2000", "3000" },
                { "1000", "2000", "3000" }, { "sept", "siete", "sette" } };

        DefaultTableModel dtm = new DefaultTableModel(tableData, columnNames);
        table.setModel(dtm);
        // dtmView.fireTableDataChanged();
        dtm.fireTableStructureChanged();
    }
