bug 6068, 6933. nsTableRowGroupFrame::CalculateRowHeights - changed row spans to consider
top and bottom margins during height calculations. Calculations using percentages ensure that the sum of
rows sum exactly to excess.
bug 6404 BasicTableLayoutStrategy::BalanceColumnsConstrained cols in span other than 1st col was
not getting additional allocations from cell. ::DistributeRemainSpace uses max width of col
instead of max effective width. Also added checks for negative value during percentage calculations.
and/or to the width attribute on the table itself), the rule is to try to give the column the largest value
assigned to it by any cell intersecting that column.
Separate storage is maintained for a column's natural desired width (width from any source other than a cell
with a colspan) and the maximum contribution to the column's width from any cell with a colspan.
nsHTMLAtoms.cpp,h added some HTML 4 strings for tables
nsHTMLParts.h added constructors for new table content classes
nsGenericHTMLElement.cpp,h added table frame creation, common table attribute parsing
nsHTMLTable*Element.cpp these are the new table content classes
nsHTMLContentSink.cpp enabled the new content and removed the old
nsHTMLStyleSheet.cpp fixed the table style optimizations to work with new content
nsTable*Frame.cpp these work with the new content
aFilter is useful for determining if a frame should output itself during
a List(). In any event, the children of the frame are always processed.
added nsIListFilter, an interface for any object that wants to act like a filter for frame dumps
added static NS_LAYOUT nsIListFilter * GetFilter(nsString *aFilterName);
currently, only TableListFilter implements nsIListFilter.
in response to List(...TableListFilter), the frame model is dumped in a way that is useful
for table layout regression testing. Currently this is controlled by command line switches on the viewer app.
* fixed more margin code. we're inching towards correctness.
* the width contributed by a colspanning cell is now proportionately distributed to the columns based on the columns "effective width"
* added logic for handling illegal COLS attribute on a table (like COLS=4 in a 3-column table). See nsTableFrame::GetEffectiveCOLSAttribute()
* added logic for handling illegal COLSPAN attribute on a cell (like COLSPAN=4 in a 3-column table). See nsTableFrame::GetEffectiveColSpan(). This is wrong, and will get reworked soon.
* added the ability for cell width attributes to effect column width like Nav4.
this work exposed a few bugs and slow spots, which have been fixed
for the aol page, I added some additional backwards compatibility code
to proportionately distribute width when a fixed-width cell has colspans
