JTable Mouse Click

I have 2 JTables; table1 and table2. table1 contains the data from the database whilst table2 holds no data, atleast not yet.

What I wanted to do is that when I double click a row in table1, that specific row will be displayed in table2 so on and so forth.

Here's my code so far:

//Table1: (This is just some few codes, I didnt bother putting all of the codes 
        // since this is self explanatory)

    public void tabledbinfo() {
    con = mysqlConnection.dbConnector();
    String sql = "select main_id,cat_name,product_name,amount_value from main " +
                 "inner join category " +
                 "on main.catId = category.catId "+
                 "inner join product "+
                 "on main.proId = product.proId "+
                 "inner join price " +
                 "on main.priceId = price.priceId ";    
    try {
        prs = con.prepareStatement(sql);
        rs = prs.executeQuery();
        Object[] trow;

        while(rs.next()) {
            trow = new Object[]{rs.getString(1),
                    rs.getString(2),
                    rs.getString(3),
                    rs.getString(4)};

            dtm.addRow(trow);
        }

    } catch (SQLException e) {

        e.printStackTrace();
    }
        }



    public void tablemodel(){
    dtm = new DefaultTableModel(dbinfo,columns){

    public boolean isCellEditable(int row,int column){
        return false;
    }

    public Class getColumnClass(int column){
        Class returnValue;

        if ((column >= 0) && (column < getColumnCount())){
            returnValue = getValueAt(0,column).getClass();
        }else{
            returnValue = Object.class;
        }
        return returnValue;
    }
};
