        while(rs.next()) {

            Vector<Object> row = new Vector<Object>();

            row.add(rs.getString("description"));

            dtm.addRow(row);

        } // loop

        dtm.setDataVector(data , header);
        JScrollPane scrollPane = new JScrollPane(table);

        scrollPane.setBounds(0,0,490,250);
        panel.add(scrollPane);
        validate();

    }catch(Exception e){
        System.out.println("Error in table: "+e);
    }//try and catch

}

You can use your data Vector to store all your results/rows and then dtm.setDataVector(data , header); after the loop.

Change your code

dtm.addRow(row);

to

data.add(row);

Basically, your code have to be

    Vector<Vector<Object>> data = new  Vector<Vector<Object>>();

    while(rs.next()) {

        Vector<Object> row = new Vector<Object>();

        row.add(rs.getString("description"));
        row.add(rs.getString("amount")); 
        row.add(rs.getString("remarks")); 
        row.add(rs.getString("date"));


        data.add(row); // add each result/row to data Vector

    } // loop

    dtm.setDataVector(data , header); // load all the table rows to DefaultTableModel
