Are there any best practices for aligning buttons within a table when using PHP for form submission?

When aligning buttons within a table in PHP for form submission, it is best practice to use CSS to style the buttons and ensure they are properly aligned. You can use CSS classes to style the buttons and apply them to the table cells containing the buttons for consistent alignment.

```php
echo '<table>';
echo '<tr>';
echo '<td><button class="btn">Submit</button></td>';
echo '<td><button class="btn">Cancel</button></td>';
echo '</tr>';
echo '</table>';
```

In the above code snippet, we are using CSS classes to style the buttons within the table cells. This helps in aligning the buttons properly within the table when using PHP for form submission.
