if内のwhileを次のように置き換えます:
echo '<table class="table table-striped table-bordered table-hover">';
echo "<tr><th>Name</th><th>Description:</th><th>Status</th></tr>";
while($row = mysqli_fetch_array($results))
{
echo "<tr><td>";
echo $row['name'];
echo "</td><td>";
echo $row['des'];
echo "</td><td>";
echo $row['status'];
echo "</td></tr>";
}
echo "</table>";
