What are common challenges faced when trying to format tables in PHP?

One common challenge when formatting tables in PHP is ensuring that the table structure is consistent and visually appealing. To solve this, you can use CSS styles to define the appearance of the table elements such as borders, padding, and alignment.

echo '<table style="border-collapse: collapse;">';
echo '<tr>';
echo '<th style="border: 1px solid black; padding: 5px;">Header 1</th>';
echo '<th style="border: 1px solid black; padding: 5px;">Header 2</th>';
echo '</tr>';
echo '<tr>';
echo '<td style="border: 1px solid black; padding: 5px;">Data 1</td>';
echo '<td style="border: 1px solid black; padding: 5px;">Data 2</td>';
echo '</tr>';
echo '</table>';
