I wanted to discuss table headers since most authors disclude these when marking up tabular data. I know that a lot of the time these attributes aren't needed and can cause more of an annoyance issue with screen readers (thus most people not using these), but some times these are needed and unused.
I tend to wonder if a lot of authors don't know what these are or just forgetful thinking?
I use table headers usually for microformatted hcalendar events when I want to import certain headers.
So my question being is do you guys/girls use header attributes or leave these out(in cases where headers are needed)?
