* Column spans
* Row spans
- The spec says that if the `val` attribute is ommitted, its value
should be assumed to be `continue`, and that its values are
restricted to {`restart`, `continue`}. If the value has any other
value, I think it seems reasonable to default it to `continue`. It
might cause problems if the spec is extended in the future by adding
a third possible value, in which case this would probably give
incorrect behaviour, and wouldn't error.
* Allow multiple header rows
* Include table description in simple caption
- The table description element is like alt text for a table (along
with the table caption element). It seems like we should include
this somewhere, but I’m not 100% sure how – I’m pairing it with the
simple caption for the moment. (Should it maybe go in the block
caption instead?)
* Detect table captions
- Check for caption paragraph style /and/ either the simple or
complex table field. This means the caption detection fails for
captions which don’t contain a field, as in an example doc I added
as a test. However, I think it’s better to be too conservative: a
missed table caption will still show up as a paragraph next to the
table, whereas if I incorrectly classify something else as a table
caption it could cause havoc by pairing it up with a table it’s
not at all related to, or dropping it entirely.
* Update tests and add new ones
Partially fixes: #6316
The Builder.simpleTable now only adds a row to the TableHead when the
given header row is not null. This uncovered an inconsistency in the
readers: some would unconditionally emit a header filled with empty
cells, even if the header was not present. Now every reader has the
conditional behaviour. Only the XWiki writer depended on the header
row being always present; it now pads its head as necessary.
- Writers.Native is now adapted to the new Table type.
- Inline captions should now be conditionally wrapped in a Plain, not
a Para block.
- The toLegacyTable function now lives in Writers.Shared.
