* fixes sample6, yahoo resizing
* added BasicTableLayoutStrategy::ColIsSpecifiedAsMinimumWidth helper function,
which tells us if the given column has a width attribute that means "make me as small as possible"
* nsTableFrame methods now no longer use mCellMap directly, they ask for it from
GetCellMap which gets the cell map from the first-in-flow. Only the first-in-flow has a
cell map because the cellmap refers to the table as a single object, not to each table frame.
* Likewise, continuing table frames do not call BalanceColumnWidths or SetTableWidth
which are "global" operations. Responsibility for these lies with the first-in-flow.
for nonsense COLSPANs at the edge of a table. Fixed some bugs this uncovered
where the cell was being asked for its colspan attribute rather than the table
being asked for the cell's effective col span.
* 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
Made DidSetStyleContext virtual, since we need to override the behavior in subclasses
Moved attribute setting logic from nsTableCell to nsTableCellFrame
Table Borders are being drawn again : )
Table Padding is being displayed
table column balancing. Implemented in BasicTableLayoutStrategy (HTML4-spec).
nsTableFrame instantiates a strategy depending on the compatibility mode.
