Table subtotals on every page

Bartosz Majkut

Hello Everyone,
I need to find best tool for report generating for my project. Main issue during searching is always with subtotals for table on every page.
Here using chrome-pdf and handlebars I can see I probably need to use double rendering mechanism. I know how to add data to every page like table row value but I don't have any idea how to calculate subtotal for particular page and fill that during second render.
I am trying smth like this:

*<html>
    <head>
        <meta content="text/html; charset=utf-8" http-equiv="Content-Type">
    </head>
    <body>
        <table style="border: 2px solid black;">
            <thead>
                <tr>
                    <th style="min-width: 350px;">
                        Item
                    </th>
                    <th style="min-width: 150px;">
                        Price
                    </th>
                </tr>
            </thead>
            <tbody>
                {{#each items}}
                <tr class="item">
                    <td>
                        {{name}}
                    </td>
                    <td style="text-align: center;">
                        {{price}} zł {{{pdfAddPageItem price}}}
                    </td>
                </tr>
                {{/each}}
            </tbody>
            <tfoot>
                <tr>
                    <td>
                    Suma: 
                    </td>
                        <td
                            style="text-align: center;">
                            {{pageNumber}} zł
                        </td>
                </tr>
            </tfoot>
        </table>
    </body>
</html>*

Thanks in advance for every advice!

I've tried the idea with the second render.
In the first render, I add an empty tfoot which will just hold the space.
In the second render I won't add tfoot, but instead, add an extra plain row with a calculated sum value.

Here is the demo
