Re: Non-textual content: tables?

HI,


The simple answer is no. If the table is correctly marked up using HTML table tags. Then you will pass the 1.3.1 requirement. 1.1.1 focuses upon images, not how a page is structured.

1.1.1 is leveraged when you have a image showing something. Such as a graph, logo, picture, etc. Then you can apply alt text or other techniques to the image. So screen reader users can understand the image. In the case of an graph (chart) I would recommend there is an HTML table on the page showing the same information or summary. The screen reader user or other users who cannot understand graphs have the ability of seeing the raw data or a summary of the key points from the graph. The table you do not apply any alt text concepts to it. You can apply a summary or caption to the table if you like.

Hi,

Thank you so much for clarifying. Reading the criteria 1.3.1: Information, structure, and relationships conveyed through presentation can be programmatically determined or are available in text. My question now is that if the table is correctly structured and is regular (no merge cells, etc), and the information regarding this table or a summary of the most important values contained is provided in the text, must the table have also an alternative text according to these criteria (1.1.1 and 1.3.1)?

The problem is that some of the people are complaining about this, as in the Word file you can add alternative text for a table, but when exporting to PDF, you have to manually add table summary, because although the text is exported in the table tag, only is read by screen readers if you add a table summary, which implies a doble work for the people.

Thank you.

Hi Vera

A table is not non-textual content; a table is a structure that should be marked up as such with prober headings, a caption and a summary. Rather than SC 1.1.1., you probably want to have a look at SC 1.3.1.

Venligst/Kind regards

Hello,

Our country adopted the EN 301 549:2019 norm/standard, which is based on WCAG 2.1 guidelines. I have a question regarding the 1.1.1 success criteria, which is non-textual content. In concrete, I cannot find anywhere how the tables should be considered. We are sure that figures must have an alternative text as they are non-textual content, but our doubt is with the tables, we do not know how they should be considered, and we couldn't find any solid clarification in the norm/standard.

Please can you help us?

Thank you,
Regards,
Vera.
