What is the potential issue with the code provided for reading a CSV file into a table?

The potential issue with the provided code is that it is not handling errors that may occur while reading the CSV file. To solve this, we should add error handling to catch any exceptions that may be thrown during the file reading process. 

<?php

$filename = 'data.csv';

try {
    $file = fopen($filename, 'r');
    
    if ($file === false) {
        throw new Exception("Error opening file");
    }
    
    echo "<table>";
    
    while (($data = fgetcsv($file)) !== false) {
        echo "<tr>";
        foreach ($data as $value) {
            echo "<td>" . htmlspecialchars($value) . "</td>";
        }
        echo "</tr>";
    }
    
    echo "</table>";
    
    fclose($file);
} catch (Exception $e) {
    echo "Error: " . $e->getMessage();
}

?>
