Hello Herman,

thanks for your reply.

The above example has already helped me a lot to get started.

Accessibility requirements for documents are already regulated by EU law and will become punitive from mid-2025. In this context, I need tables that are properly tagged so that they can be read aloud with the appropriate tools (e.g. screen reader). So I am looking for a fitting API. According to the recommendations on the accessibility of PDF files on the Internet I found, tables should be tagged as follows:

<table>
<thead>
<tr>
<th scope="col">Headline 1</>
<th scope="col">Headline 2</>
<th scope="col">Headline 3</>
</tr>
</thead>
</tbody>
<tr>
<th scope="row">Rowline 1</>
<td>ABC</>
<td>CDE</>
</tr>
<tr>
<td scope="row">Rowline 2</>
<td>FGH</>
<td>IJK</>
</tr>
<t/body>
</table>

The scope attribute allows the heading to be read out for each cell.

I have already managed the nested tag structure. However, I can't get the cell contents into the tags (th and td), they are all together still in the table tag <table>. Furthermore, I can't get the scope attribute to work as an attribute.

I test the table structure with the program PAC 2021 (PDF Accessiblity Checker 2021, Button: Logical Structure).

I would be grateful for a few suggestions or examples.

Kind regards
Uwe

Hello,

Do you want that the table of output PDF is created by "<table>" attribute like in the screenshot below?

CCB20E33-E4E3-4fd1-8B3A-DA4201A1D302.png

Currently our product created it by the path attribute. I attached our current generated PDF here. Can you provide us with an example document for this <table> attribute? And then our developers will do more investigations to check if there is any approach can fulfill your requirements.If there is any misunderstanding, please also provide more information such as some document and screenshots, so that we can investigate your issue accurately. Thanks in advance.

Hallo Herman,

thanks for your reply.

I need the tags inside the table, like THead, TBody, TR, TH, TD (PDFStandardStructTypes) and also the specification of attributes.

I can't get the content into the last tag (<TH> or <TD>) and also the specification of attributes. There I would be grateful for an example.

Attached are a few examples of how it might look. In the Word example the specification of the scope attribute is still missing, otherwise this is already very good. In the HTML example the tags and the attributes are ok, only there I can't determine the layout exactly.

Kind regards
Uwe
