element encloses rows to identify them as header rows. It doesn't display anything in itself.
The th
element is an actual cell that will contain header content to be displayed. It would be inside a row.
As to the scope attribute, it's true that heading cells in a thead
row would generally relate to a column, but their might be some value (perhaps for styling or scripting) in explicitly defining their scope with the attribute.
The potential uses of the thead
element and the scope
attribute are not quite the same. The thead
indicates entire rows containing heading header information. This could be used to include the header rows on each page of a printed, multi-page table, or to present a long table with a scrolling body and static header rows.
The scope
attribute defines which cells a specific th
header cell relates to. The th
element is not only used for column headers, nor is it restricted to rows in a thead
. The scope
attribute might be used to give special styling to certain header cells based on their function.

4,479 PointsThe scope="col" as well as thead element don't display anything in itself, so i don't get your point.
My question was why would you use both simultaneously when they achieve same exact thing.

231,236 PointsIt depends on how you use them, they could be used for the same thing, but their usage could also be very different. I extended my original answer with some examples.

Front End Web Development Techdegree Student 2,777 PointsAs far as I understand it, <thead>
is a kind of wrapper, like <div>
or <section>
, when you need to wrap elements to target them with CSS.
