Re: Layout or data table?

I agree with Elizabeth that a heading (H2 etc) should often be used also, since sometimes screen-reader users will navigate by heading or ask for a list of headings to be read out; in that scenario an important table with a perfectly valid CAPTION would not be announced since H1 - H6 was not used with the TABLE.


I had wrongly remembered that headings are not valid inside CAPTION, but it looks like in HTML *4* it was not valid

https://www.w3.org/TR/html401/struct/tables.html#edef-CAPTION

but in HTML5 it IS valid

https://html.spec.whatwg.org/multipage/tables.html#the-caption-element


This approach, use of H2 (3, 5, etc) inside a "heading like tag", is also valid and valuable when using the LEGEND tag with FIELDSET

Louise:

I agree with Alan Bristow that there are multiple ways to present the information including as a data table. If it were me, I would add a header row at the top for Title, Name and make both <th scope="col"> cells.

A <caption> should also be present, but I did have a screen reader user comment that they wanted one of the <h> tags  for each table in addition to captions. If it's possible to embed an <h2> inside a <caption>, that would probably work. You could probably use CSS for when <h2> is inside a caption.

Hope this helps.
Elizabeth

Hello all,

I hope you can assist.

On our website we have some tables that contain information on committee member names and their roles, so for example:

Committee members

Chair

Mr A*

Treasurer

Mrs Y

Ordinary member

Mr C

Ordinary member

Mr G

Ordinary member

Ms P


In this case, the title is a h2 and each role in the left-hand cell carries the <th scope> value.  To all intents and purposes, we have treated it as a data table, but is it a layout table because the information could be presented in linear fashion another way? And if so, should it have a role="presentation" value in it?

I feel this is a bit of a grey area between the two and would appreciate your thoughts. It reads out fine in NVDA so I don't think it's an issue, but wanted to make sure we were accounting for our tables correctly!

With thanks
Louise
