The content of table cells should largely be handled by the general writing-mode support being implemented throughout layout; but the layout of the table as a whole (columns and rows) also needs to be handled. This may be deferred to a later milestone than the initial release of vertical support for "simple" content.

Layout of content of table cells in vertical writing-mode --------------------------------------------------------- table-cell and 'vertical-rl' - block flow direction of block-level boxes http://www.gtalbot.org/BrowserBugsSection/CSS3WritingModes/wm-block-flow-direction-011.xht table-cell and 'vertical-lr' - block flow direction of block-level boxes http://www.gtalbot.org/BrowserBugsSection/CSS3WritingModes/wm-block-flow-direction-012.xht Layout of table as a whole: row progression tests ------------------------------------------------- vertical-rl - table rows progression (basic) http://www.gtalbot.org/BrowserBugsSection/CSS3WritingModes/wm-row-progression-002.xht vertical-lr - table rows progression (basic) http://www.gtalbot.org/BrowserBugsSection/CSS3WritingModes/wm-row-progression-003.xht vertical-rl - table rows progression and colspan http://www.gtalbot.org/BrowserBugsSection/CSS3WritingModes/wm-row-progression-004.xht vertical-lr - table rows progression and colspan http://www.gtalbot.org/BrowserBugsSection/CSS3WritingModes/wm-row-progression-005.xht vertical-rl - table rows progression and rowspan http://www.gtalbot.org/BrowserBugsSection/CSS3WritingModes/wm-row-progression-006.xht vertical-lr - table rows progression and rowspan http://www.gtalbot.org/BrowserBugsSection/CSS3WritingModes/wm-row-progression-007.xht Those 8 tests all use the same reference file: http://www.gtalbot.org/BrowserBugsSection/CSS3WritingModes/multicol-count-002-ref.xht

Layout of content of table cells in vertical writing-mode --------------------------------------------------------- table-cell and 'vertical-rl' - ordering direction of line boxes http://www.gtalbot.org/BrowserBugsSection/CSS3WritingModes/wm-line-box-direction-011.xht table-cell and 'vertical-lr' - ordering direction of line boxes http://www.gtalbot.org/BrowserBugsSection/CSS3WritingModes/wm-line-box-direction-012.xht

Note that a number of the tests in reftests/writing-mode/ua-style-sheet-* that involve tables currently have their vertical writing-mode portions commented out. We should uncomment these once vertical layout is supported.

Firefox (4/22/2015 Aurora) seems to have the same bug in tables that Chrome has, namely cell content overflows when children of cells are given a vertical writing-mode. See https://code.google.com/p/chromium/issues/detail?id=410320 for a description of the bug and testcase showing the error.

Quick draft test on orthogonal table cell based on latest comments 94 and 95 in bug 145503 and also based on [CSSWG] Minutes New York F2F 2015-05-19 Part I: Writing Modes: Deferring Orthogonal Table Cells http://lists.w3.org/Archives/Public/www-style/2015May/0313.html http://www.gtalbot.org/BrowserBugsSection/CSS3WritingModes/s73-orthogonal-table-cell-003.xht This test is, I guess, okay, acceptable for now; its filename may change in the future. When I have done more orthogonal table-cell tests and when such orthogonal table-cell tests are more reliable and mature, then I will create another bug report and I will make it blocking this bug 1077521.

When I have more time, I will create tests based on your description. This whole thing is still *very tricky* as - browsers have quirks and many bugs on table cell rendering - overflow applies to non-replaced table cells, including overflow: visible

Yes. This http://www.gtalbot.org/BrowserBugsSection/CSS3WritingModes/s73-orthogonal-table-cell-003.xht test most likely deserves to be available too for bug 1166120

Just for your information. These 2 tests table-cell and 'vertical-rl' - ordering direction of line boxes http://www.gtalbot.org/BrowserBugsSection/CSS3WritingModes/wm-line-box-direction-011.xht table-cell and 'vertical-lr' - ordering direction of line boxes http://www.gtalbot.org/BrowserBugsSection/CSS3WritingModes/wm-line-box-direction-012.xht now pass in Firefox latest nightly build (41.0a1 buildID = 20150622052959).

Maybe it's time to do this... table support is some way from complete yet, but I think there's enough of it that we can usefully turn it on and start adding tests, and we don't need this "protecting" us any longer.

Here are a couple of basic sanity-test reftests for vertical table layout. Obviously there'll be more to come...

More testcases.

Pushed the CSS change and initial reftests here, but let's keep the bug open for at least a few more testcase before marking it fixed.

I backed out the reftests for failures on at least Android. https://treeherder.mozilla.org/logviewer.html#?job_id=11033471&repo=mozilla-inbound https://hg.mozilla.org/integration/mozilla-inbound/rev/d854bedb4980

The leave-open keyword is there and there is no activity for 6 months. :jfkthame, maybe it's time to close this bug?

I guess we can close this, as the feature is basically working; and make the remaining open dependencies here directly block the main writing-mode meta bug.
