Description Mike Lawther 2013-01-21 15:57:32 PST 
Our calc() implementation produces a different result from Mozilla when used in tables. This bug is to document that a difference exists.

Note that this is acceptable per spec (http://www.w3.org/TR/css3-values/), as an implementation is allowed to treat a calc() inside a table as if 'auto' had been specified.

Mozilla's test suite can be found here: http://mxr.mozilla.org/mozilla-central/source/layout/reftests/w3c-css/submitted/values3/

The tests that differ are:
 * calc-width-table-fixed-1.html
 * calc-width-table-auto-1.html

The third row of the test still fails on Safari 15.
