TUG 2022 —Ross Moore — Accessible tables using Tagged PDF

Some basic requirements for Accessibility of tabular material are: each cell, whether header or content, must have an attribute providing a unique ID for that cell; each data cell must specify the corresponding row and column headers that most directly provide the meaning of the information contained within the cell. This is done via a Headers attribute using the unique IDs for the header cells. Header cells themselves may have other row or column headers; e.g., as a common header for a block of rows or columns. Tagged PDF has the tagging and mechanisms to provide such attributes. When the PDF is translated into HTML (using the ngPDF online converter, say) this information is recorded in the web-pages, to be available to Assistive Technologies. In this talk we show several examples of tables specified using various packages, as in the LaTeX Companion, both in PDF and HTML web pages. A novel coding idea that allows this to be achieved will be presented.
