RE: Layout or data table?

Thanks for all your thoughts on this. So basically you’d end up with something like this:

<table>
              <caption>
              <h2>Committee members</h2>
              </caption>
              <thead>
                             <tr>
                                           <th scope="col">Role</th>
                                           <th scope="col">Name</th>
                             </tr>
              </thead>
              <tbody>
                             <tr>
                                           <td>Chair</td>
                                           <td>Mr A</td>
                             </tr>
                             <tr>
                                           <td>Treasurer</td>
                                           <td>Mrs C</td>
                             </tr>
                             <tr>
                                           <td>Ordinary member</td>
                                           <td>Ms B</td>
                             </tr>
              </tbody>
</table>

Have I got that right 😊? Do you think having ‘role’ and ‘name’ is overkill for the information presented? Or is it better practice no matter how simple the content? Sorry this is probably obvious to some of you!

I might be in the minority here, but personally I greatly dislike overuse of Headings I find on some sites. If there is a H4 / H5 indicating the start of Officers and the start of Staff members, I would be fine with that, but a H2 for each and every staff member without extensive information about that staff member (address/phone/email) would make me switch my screen reader to ignore headings for that Site.


Thanks!
Jonathan

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<https://gbr01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.w3.org%2FTR%2Fhtml401%2Fstruct%2Ftables.html%23edef-CAPTION&data=04%7C01%7Clouise.lister%40iop.org%7Cd996663c46464e44b0f808d8f9d65904%7C8b8986af18bb4882a149fa5a3dd1f995%7C0%7C0%7C637534046306615394%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=HrdcZUNjwc2MjGsSmnJCFSnRYoXgPE6PnnDgQC6wOqs%3D&reserved=0>

but in HTML5 it IS valid

https://html.spec.whatwg.org/multipage/tables.html#the-caption-element<https://gbr01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fhtml.spec.whatwg.org%2Fmultipage%2Ftables.html%23the-caption-element&data=04%7C01%7Clouise.lister%40iop.org%7Cd996663c46464e44b0f808d8f9d65904%7C8b8986af18bb4882a149fa5a3dd1f995%7C0%7C0%7C637534046306615394%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=PBXCz9Weqcm1Ic6ZW0neAV2IJPNqUy03IhOQUcRdu2E%3D&reserved=0>



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
