Pergunta
A co-worker and I are curious about when colspan
and rowspan
became available for usage in HTML tables.
We tried Google and Wikipedia, but the answer still seems to elude us.
I thought it might have been since HTML 2, or early-to-mid-90s, but he insists it wasn't until 2000 or later....
Solução
RFC 1942 introduced tables in May 96, the rfc includes rowspans so this is the earliest official document implementing them.
http://tools.ietf.org/html/rfc1942
Edit - Should mention that this is a refinement for html 2.0
Outras dicas
They're mentioned in versions of the HTML 4 spec as far back as 1997 at least. edit They're also in HTML 3; they seem to have been around as long as <table>
itself.
As far as W3C is concerned, it looks like HTML 3.2, so January 1997. Both attributes are mentioned in the 3.2 spec, but I don't see them anywhere in the 2.0 spec.
If you're not strictly following W3C, the answer seems to be May 1996. See the example at the top of page 2 of RFC 1942, which adds support for tables.
Well they are in HTML3: http://www.w3.org/MarkUp/html3/tables.html
