    <tr>
        <td   width= "105 "> <input   name= "ipaddress1 "   type= "text "   size= "15 "> </td>
            <td   width= "63 "> <input   name= "serialno1 "   type= "text "   size= "15 "> </td>
                <td   width= "10 "> <input   name= "route1 "   type= "text "   size= "15 "> </td>
    </tr>
    <tr>
        <td> <input   name= "ipaddress2 "   type= "text "   size= "15 "> </td>
            <td> <input   name= "serialno2 "   type= "text "   size= "15 "> </td>
                <td> <input   name= "route2 "   type= "text "   size= "15 "> </td>
    </tr>
    <tr>
