jtable更新数据

  static JTable table;

    public void refrushTableData() {

        String[] columnNames = { "", "", "" };

        String[][] tableData = { { "", "", "" },

                { "", "", "" }, { "sept", "siete", "sette" } };

        DefaultTableModel dtm = new DefaultTableModel(tableData, columnNames);

        table.setModel(dtm);

        // dtmView.fireTableDataChanged();

        dtm.fireTableStructureChanged();

    }
