tables and ODF 1.2 draft 7-3

Regarding http://www.oasis-open.org/apps/org/workgroup/office/download.php/28461/OpenDocument-v1.2draft7-3.odt

The text of the is-sub-table section
changed slightly, There was no concern about this section.

19.936 table:is-sub-table 

The table:is-sub-table attribute specifies
if a nested table is a subtable. 

If a table cell only contains a single
table but no paragraphs or other content, this table can be specified as
subtable. It then occupies the whole cell and no other content can appear
in this cell.

The borders of a subtable merge with
the borders of the cell that it resides in. A subtable does not have its
own style. A subtable is essentially a container for some additional table
rows that integrate seamlessly with the parent table.

A nested table that is not a specified
to be a subtable appears as a table within a table, that is, it has borders
distinct from those of the parent cell and respects the padding of the
parent cell.

Ed. Note: The examples have
been removed, since they implied that is-sub-table is appropriate for simulating
row- and colspan.

The text in section E.3 Tables in Presentations
has not changed and thus Rich's issue with the TC remains open.  Rich's
note from May 10 follows this note.

E.3.Tables in Presentations

Users importing non-OpenDocument slides
that contain tables need access to the table structure via their assistive
technology. Therefore tables imported into an OpenDocument application
from another file format must have their structure preserved, and when
saved as OpenDocument should be saved as as embedded spreadsheets.

Re: [office-accessibility] tables and
latest ODF specLink

ODF TC: 

In Pete's review of the current internal
TC draft of the ODF 1.2 specification it is unclear that native table support
has been added to presentations in ODF 1.2. This is something

the accessibility SC had asked for in
1.1 but was being deferred until 1.2.

Native table support in presentations
may be indicated in the schema but that has not been provided in the current
release of the specification.

Since access to structural information
is so important, especially for tables, would members of the TC indicate
when this will be provided

for in the 1.2 specification?

Pete,I responded to your note below.
Thanks for the analysis. 

Thank you,

Rich

Yes, what this tells me is that the current 1.2 specification,
as written, does

not clearly articulate that native table support is
in presentations. What this says is that in order

to render a table you essentially need to do what
was done in 1.1 which is to treat the

table as an embedded spreadsheet (such as through
OLE embedding) which would be accessible.

This was inconsistent with what we had been told should
be in 1.2. What makes this more difficult is 

we don't have a schema to verify. The Schema should
indicate if native table support is provided.

If we had native table support there should be no
need for this. If native table support is not added then I agree 

we would need to correct the link.
