/******************************************************************************************
|
|
* During the initial reflow the table reflows each child with an unconstrained avail width
|
|
* to get its max element width and maximum width. This is referred to as the pass 1 reflow.
|
|
*
|
|
* After the 1st pass reflow, the table determines the column widths using BalanceColumnWidths()
|
|
* then reflows each child again with a constrained avail width. This reflow is referred to
|
|
* as the pass 2 reflow.
|
|
*
|
|
* A special height reflow (pass 3 reflow) can occur during an intitial or resize reflow
|
|
* if (a) a row group, row, cell, or a frame inside a cell has a percent height but no computed
|
|
* height or (b) in paginated mode, a table has a height. (a) supports percent nested tables
|
|
* contained inside cells whose heights aren't known until after the pass 2 reflow. (b) is
|
|
* necessary because the table cannot split until after the pass 2 reflow. The mechanics of
|
|
* the special height reflow (variety a) are as follows:
|
|
*
|
|
* 1) Each table related frame (table, row group, row, cell) implements NeedsSpecialReflow()
|
|
* to indicate that it should get the reflow. It does this when it has a percent height but
|
|
* no computed height by calling CheckRequestSpecialHeightReflow(). This method calls
|
|
* RequestSpecialHeightReflow() which calls SetNeedSpecialReflow() on its ancestors until
|
|
* it reaches the containing table and calls SetNeedToInitiateSpecialReflow() on it. For
|
|
* percent height frames inside cells, during DidReflow(), the cell's NotifyPercentHeight()
|
|
* is called (the cell is the reflow state's mPercentHeightObserver in this case).
|
|
* NotifyPercentHeight() calls RequestSpecialHeightReflow().
|
|
*
|
|
* 2) After the pass 2 reflow, if the table's NeedToInitiateSpecialReflow(true) was called, it
|
|
* will do the special height reflow, setting the reflow state's mFlages.mSpecialHeightReflow
|
|
* to true and mSpecialHeightInitiator to itself. It won't do this if IsPrematureSpecialHeightReflow()
|
|
* returns true because in that case another special height reflow will be coming along with the
|
|
* containing table as the mSpecialHeightInitiator. It is only relevant to do the reflow when
|
|
* the mSpecialHeightInitiator is the containing table, because if it is a remote ancestor, then
|
|
* appropriate heights will not be known.
|
|
*
|
|
* 3) Since the heights of the table, row groups, rows, and cells was determined during the pass 2
|
|
* reflow, they return their last desired sizes during the special height reflow. The reflow only
|
|
* permits percent height frames inside the cells to resize based on the cells height and that height
|
|
* was determined during the pass 2 reflow.
|
|
*
|
|
* So, in the case of deeply nested tables, all of the tables that were told to initiate a special
|
|
* reflow will do so, but if a table is already in a special reflow, it won't inititate the reflow
|
|
* until the current initiator is its containing table. Since these reflows are only received by
|
|
* frames that need them and they don't cause any rebalancing of tables, the extra overhead is minimal.
|
|
*
|
|
* The type of special reflow that occurs during printing (variety b) follows the same mechanism except
|
|
* that all frames will receive the reflow even if they don't really need them.
|
|
*
|
|
* Open issues with the special height reflow:
|
|
*
|
|
* 1) At some point there should be 2 kinds of special height reflows because (a) and (b) above are
|
|
* really quite different. This would avoid unnecessary reflows during printing.
|
|
* 2) When a cell contains frames whose percent heights > 100%, there is data loss (see bug 115245).
|
|
* However, this can also occur if a cell has a fixed height and there is no special height reflow.
|
|

* cell, row, rowgroup, col, colgroup, table

/* Here is the order for storing border edges in the cell map as a cell is processed. There are
|
|
n=colspan top and bottom border edges per cell and n=rowspan left and right border edges per cell.
|
|
|
|
1) On the top edge of the table, store the top edge. Never store the top edge otherwise, since
|
|
a bottom edge from a cell above will take care of it.
|
|
2) On the left edge of the table, store the left edge. Never store the left edge othewise, since
|
|
a right edge from a cell to the left will take care of it.
|
|
3) Store the right edge (or edges if a row span)
|
|
4) Store the bottom edge (or edges if a col span)
|
|
|
|
Since corners are computed with only an array of BCCornerInfo indexed by the number-of-cols, corner
|
|
calculations are somewhat complicated. Using an array with number-of-rows * number-of-col entries
|
|
would simplify this, but at an extra in memory cost of nearly 12 bytes per cell map entry. Collapsing
|
|
borders already have about an extra 8 byte per cell map entry overhead (this could be
|
|
reduced to 4 bytes if we are willing to not store border widths in nsTableCellFrame), Here are the
|
|
rules in priority order for storing cornes in the cell map as a cell is processed. top-left means the
|
|
left endpoint of the border edge on the top of the cell. There are n=colspan top and bottom border
|
|
edges per cell and n=rowspan left and right border edges per cell.
|
|
|
|
1) On the top edge of the table, store the top-left corner, unless on the left edge of the table.
|
|
Never store the top-right corner, since it will get stored as a right-top corner.
|
|
2) On the left edge of the table, store the left-top corner. Never store the left-bottom corner,
|
|
since it will get stored as a bottom-left corner.
|
|
3) Store the right-top corner if (a) it is the top right corner of the table or (b) it is not on
|
|
the top edge of the table. Never store the right-bottom corner since it will get stored as a
|
|
bottom-right corner.
|
|
4) Store the bottom-right corner, if it is the bottom right corner of the table. Never store it
|
|
otherwise, since it will get stored as either a right-top corner by a cell below or
|
|
a bottom-left corner from a cell to the right.
|
|
5) Store the bottom-left corner, if (a) on the bottom edge of the table or (b) if the left edge hits
|
|
the top side of a colspan in its interior. Never store the corner otherwise, since it will
|
|
get stored as a right-top corner by a cell from below.
|
|
|
|
XXX the BC-RTL hack - The correct fix would be a rewrite as described in bug 203686.
|
|
In order to draw borders in rtl conditions somehow correct, the existing structure which relies
|
|
heavily on the assumption that the next cell sibling will be on the right side, has been modified.
|
|
We flip the border during painting and during style lookup. Look for tableIsLTR for places where
|
|
the flipping is done.
