I don’t recommend nested tables, because it takes quite some work to make it accessible for the majority of users which are sighted and use a smartphone for surfing the web!

Quite often people do a lot of thinking to support screenreaders. Actually this is quit straight forwarded: make sure every non textual content has a tex alternative and the order of elements in the source code makes sense.

Also use html as intended, which means the mail element for the main content or button element when you want a button.

In general much more effort is needed for users of other assistive technologies like screen magnifiers or even people who see quite good, but use the browser zoom.

How do nested tables look like in a window, that is not fullscreen and has a moderat zoom factor of 150%?

Quite often this will already result in horizontal scroll bars...

Mit freundlichen Grüßen
