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.
ables were not correctly applying the min width of the content of cells
that had col spans in some cases. In this case, the nested table was specified
as being too narrow for the content. There were 4 columns each with width=25%
in the first row, and in the next row a single cell with colspan=4 and whose
content min size was wider than the specified table width.
now autowidth columns as assigned a width starting from their minimum. The remaining
space is proportionately divided among them, never allowing a column to go over its max (for
autowidth tables only.)
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.
* 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.
* 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
table column balancing. Implemented in BasicTableLayoutStrategy (HTML4-spec).
nsTableFrame instantiates a strategy depending on the compatibility mode.
