http://www.w3.org/Bugs/Public/show_bug.cgi?id=13770 Summary: Take back colspan="0" and rowspan="0" for TD/TH elements Product: HTML WG Version: unspecified Platform: All OS/Version: All Status: NEW Severity: normal Priority: P2 Component: LC1 HTML5 spec (editor: Ian Hickson) AssignedTo: ian@hixie.ch ReportedBy: mtanalin@yandex.ru QAContact: public-html-bugzilla@w3.org CC: mike@w3.org, public-html-wg-issue-tracking@w3.org, public-html@w3.org http://www.w3.org/TR/html5/tabular-data.html#dom-tdth-colspan << The colSpan IDL attribute must reflect the content attribute of the same name. The value must be limited to only non-negative numbers _greater than zero_. >> In HTML4, "colspan" and "rowspan" attributes of TD/TH elements has been allowed to have zero value ("0"): http://www.w3.org/TR/html4/struct/tables.html#adef-colspan This is very useful when column or row number is unknown in advance. It's harmful to force web-editors to calculate column or row number manually while browser could easily do this automatically. There is a known rule in spec development: when there are two independent implementations of a specification, then the specification status is promoted to "recommendation" ("candidate" or "proposed"). But there ARE already two (well, 1.5) working independent implementations of zero colspan/rowspan: 1. Firefox (both zero colspan and rowspan are fully working) 2. and Opera (supports rowspan="0" and does not support colspan="0"). So, zero value of colspan/rowspan is very good candidate to keep in HTML spec and, moreover, to encourage rest browser vendors to implement this useful feature as soon as possible. There are no serious reasons to remove zero values of colspan/rowspan from the HTML specification. It's not something "unimplemented at all", it's already quite usably implemented and should be kept intact in the HTML spec.
