CSS 2.1 failure: fixed-table-layout-013 and fixed-table-layout-015 fail
https://bugs.webkit.org/show_bug.cgi?id=78027
Reviewed by Julien Chaffraix.
Source/WebCore:
Both of these test the (slightly implicit) rule that width set on column-groups cannot
affect the width of columns in a fixed layout table: http://www.w3.org/TR/CSS21/tables.html#fixed-table-layout
FF, Opera and IE all pass these two tests.
Tests: css2.1/20110323/fixed-table-layout-013.htm
css2.1/20110323/fixed-table-layout-015.htm
* rendering/FixedTableLayout.cpp:
(WebCore::nextCol): A helper function for finding the next column along.
(WebCore::FixedTableLayout::calcWidthArray): Ignore width specified by column groups.
* rendering/RenderTableCol.h:
(WebCore::RenderTableCol::isTableColGroup): Convenience function for identifying column groups.
