colspan bug at write_pdf

[SilverGeri]

I want to generate a table from a list of products then add the sum price to the end of the table. I need a signature section at the end of each page
when there are too many products and the table is split between more pages, colspan is applied to the last row of each page instead of only the last one where it is correct. I checked the generated html, it is fine but when I save it to pdf, the bug appears

         th, td {
            border: 1px solid black;
            padding: 1mm;
        }

        table {
            border-collapse: collapse;
            width: 100%;
            font-size: 12px;
            page-break-inside: auto;
        }

        tr {
            page-break-inside: avoid;
            page-break-after: auto;
        }
        thead {
            display: table-header-group;
        }

        tbody {
            border: 1px solid black;
        }

        tfoot {
            display: table-footer-group;
        }

        .footer {
            padding-top: 10mm;
            padding-bottom: 6mm;
            border-style: none;
        }

        .footer-wrapper {
            width: 46mm;
            margin-left: auto;
            text-align: center;
        }

<div style="page-break-before: always">
    <table>

            </tr>
        </thead>
        <tbody>
            {% for product in products.all %}
            <tr>
                <td>{{ forloop.counter }}</td>
                <td>{{ product.name }}</td>
                <td>{{ product.gross_price|floatformat:0 }}&nbsp;Ft</td>
                <td>{{ product.quantity }}&nbsp;{{ item.product.unit }}</td>
                <td>{{ product.total_price|floatformat:0 }}&nbsp;Ft</td>
            </tr>
            {% endfor %}
            <tr>
                <td colspan="4">Sum</td>
                <td>{{ products_total_price|floatformat:0 }}&nbsp;Ft</td>
            </tr>

                            {{ name }}
                        </span>

                </td>
            </tr>
        </tfoot>
    </table>

when there are too many products and the table is split between more pages, colspan is applied to the last row of each page instead of only the last one where it is correct.

You’re right! That’s a dirty bug…

For each page, vertical lines were drawn on the last line as they were drawn on the last page. It only happened for tables with a footer.

All previous tests pass, another one has been added, just in case…
