What are the potential pitfalls of using PHP to generate tables with a specified number of columns per row?

One potential pitfall of using PHP to generate tables with a specified number of columns per row is that if the total number of data elements is not evenly divisible by the specified number of columns, it may result in incomplete rows or missing data. To solve this issue, you can calculate the remainder when dividing the total number of data elements by the specified number of columns, and then add empty cells to the last row to make it complete. 

<?php
// Sample data array
$data = ['Cell 1', 'Cell 2', 'Cell 3', 'Cell 4', 'Cell 5', 'Cell 6', 'Cell 7', 'Cell 8', 'Cell 9'];

// Specified number of columns per row
$columns_per_row = 3;

// Calculate the number of rows needed
$num_rows = ceil(count($data) / $columns_per_row);

// Loop through the data and generate the table
echo '<table>';
for ($i = 0; $i < $num_rows; $i++) {
    echo '<tr>';
    for ($j = 0; $j < $columns_per_row; $j++) {
        $index = $i * $columns_per_row + $j;
        echo '<td>' . ($index < count($data) ? $data[$index] : '') . '</td>';
    }
    echo '</tr>';
}
echo '</table>';
?>
