In what situations might the width attribute of a table in HTML cause alignment issues in TCPDF-generated PDFs?

When using TCPDF to generate PDFs from HTML tables, the width attribute of a table can cause alignment issues if the sum of the column widths exceeds the width of the page. To solve this issue, it is recommended to use CSS styling with percentage widths for the columns instead of fixed pixel widths. This allows the table to adjust its size based on the available space in the PDF. 

$html = '<table style="width:100%">
            <tr>
                <th style="width:25%">Column 1</th>
                <th style="width:25%">Column 2</th>
                <th style="width:50%">Column 3</th>
            </tr>
            <tr>
                <td>Row 1, Cell 1</td>
                <td>Row 1, Cell 2</td>
                <td>Row 1, Cell 3</td>
            </tr>
            <tr>
                <td>Row 2, Cell 1</td>
                <td>Row 2, Cell 2</td>
                <td>Row 2, Cell 3</td>
            </tr>
        </table>';

$pdf->writeHTML($html, true, false, false, false, '');
