What are some potential pitfalls of visually representing incomplete entries in a database table output?

Visually representing incomplete entries in a database table output can lead to confusion for users as they may not be able to distinguish between complete and incomplete data. To solve this issue, it is important to clearly indicate which entries are incomplete, either by using a different color or adding a specific label to those rows. 

// Assuming we have a database table named 'users' with columns 'id', 'name', and 'email'
// We want to visually represent incomplete entries by adding a 'Incomplete' label to the rows that have missing data

$query = "SELECT id, name, email FROM users";
$result = mysqli_query($conn, $query);

echo "<table>";
echo "<tr><th>ID</th><th>Name</th><th>Email</th></tr>";

while($row = mysqli_fetch_assoc($result)) {
    echo "<tr>";
    echo "<td>" . $row['id'] . "</td>";
    echo "<td>" . $row['name'] . "</td>";
    echo "<td>" . $row['email'] . "</td>";
    if(empty($row['name']) || empty($row['email'])) {
        echo "<td>Incomplete</td>";
    }
    echo "</tr>";
}

echo "</table>";
