Answer 1

$count = 1;
while ($row = mysql_fetch_array($query)) {
    echo "<tr>";
    echo "<td>" . $count . "</td>";
    echo "<td>" . $row['id'] . "</td>";
    echo "<td>" . $row['password'] . "</td>";
    echo "<td>" . $row['position'] . "</td>";
    echo "</tr>";

    ++$count;
}

OR

$count = 1;
while ($row = mysql_fetch_array($query)) {
    echo "<tr>";
    echo "<td>" . $count++ . "</td>";
    echo "<td>" . $row['id'] . "</td>";
    echo "<td>" . $row['password'] . "</td>";
    echo "<td>" . $row['position'] . "</td>";
    echo "</tr>";
}

Answer 2

     <?php
               $num_rows = mysql_num_rows($query);
               echo "<tr>";
                   echo "<td> Total Rows".$num_rows."</td>";
               echo "</tr>";
               $i = 1;
               while ($row = mysql_fetch_array($query)) {
                    echo "<tr>";              
                   echo "<td>".$i."</td>";
                   echo "<td>".$row['id']."</td>";
                   echo "<td>".$row['password']."</td>";
                   echo "<td>".$row['position']."</td>";
                   echo "</tr>";
                   $i++;
               }
?>
