WebCore: 

        Reviewed by Darin Adler.

        - fix <rdar://problem/6032139> Table cell widths calculated
          incorrectly on table that uses table-layout:fixed, colspans, and a mix
          of percentage and pixel widths

        Test: fast/table/fixed-granular-cols.html

        The incorrect widths resulted from incorrect handling of the case where
        the <col> elements are more granular than the table cells.

        * rendering/FixedTableLayout.cpp:
        (WebCore::FixedTableLayout::calcWidthArray): When processing <col>
        elements, append effective columns or split existing effective columns
        as needed.
