Table elements char and charOff properties not supported anywhere #27830
Description
What type of issue is this?
Incorrect support data (example: BrowserX says "86" but support was added in "40")
What information was incorrect, unhelpful, or incomplete?
BCD claims that the following (deprecated) properties are supported in all browsers except Firefox:
- html.elements.col.char
- html.elements.col.charoff
- html.elements.colgroup.char
- html.elements.colgroup.charoff
- html.elements.tbody.char
- html.elements.td.char
- html.elements.tfoot.char
- html.elements.th.char
- html.elements.thead.char
- html.elements.tr.char
- html.elements.tr.charoff
As far as I can tell, they in fact have never been meaningfully supported in any browser; see e.g. the demo at https://www.hixie.ch/tests/evil/mixed/tables.html which, an a browser with real support, would align the data at the decimal point. Possibly there's some difference in whether the IDL attributes are exposed in the DOM, but I don't think this is enough to declare the feature supported.
What browsers does this problem apply to, if applicable?
No response

Can you link to any release notes, bugs, pull requests, or MDN pages related to this?
No response
Do you have anything more you want to share?
Note that this also affects the web feature https://web-platform-dx.github.io/web-features-explorer/features/table-discouraged/ although arguably that could also be fixed by splitting it into the features that were never implemented anywhere and the ones which are discouraged, but do actually work.
