1.1706 + * Before reflow, intrinsic width calculation is done using GetMinWidth
1.1707 + * and GetPrefWidth. This used to be known as pass 1 reflow.
1.1708 + *
1.1709 + * After the intrinsic width calculation, the table determines the
1.1710 + * column widths using BalanceColumnWidths() and
1.1711 + * then reflows each child again with a constrained avail width. This reflow is referred to
1.1712 + * as the pass 2 reflow.
1.1713 + *
1.1714 + * A special height reflow (pass 3 reflow) can occur during an initial or resize reflow
1.1715 + * if (a) a row group, row, cell, or a frame inside a cell has a percent height but no computed
1.1716 + * height or (b) in paginated mode, a table has a height. (a) supports percent nested tables
1.1717 + * contained inside cells whose heights aren't known until after the pass 2 reflow. (b) is
1.1718 + * necessary because the table cannot split until after the pass 2 reflow. The mechanics of
1.1719 + * the special height reflow (variety a) are as follows:
1.1720 + *
1.1721 + * 1) Each table related frame (table, row group, row, cell) implements NeedsSpecialReflow()
1.1722 + * to indicate that it should get the reflow. It does this when it has a percent height but
1.1723 + * no computed height by calling CheckRequestSpecialHeightReflow(). This method calls
1.1724 + * RequestSpecialHeightReflow() which calls SetNeedSpecialReflow() on its ancestors until
1.1725 + * it reaches the containing table and calls SetNeedToInitiateSpecialReflow() on it. For
1.1726 + * percent height frames inside cells, during DidReflow(), the cell's NotifyPercentHeight()
1.1727 + * is called (the cell is the reflow state's mPercentHeightObserver in this case).
1.1728 + * NotifyPercentHeight() calls RequestSpecialHeightReflow().
1.1729 + *
1.1730 + * 2) After the pass 2 reflow, if the table's NeedToInitiateSpecialReflow(true) was called, it
1.1731 + * will do the special height reflow, setting the reflow state's mFlags.mSpecialHeightReflow
1.1732 + * to true and mSpecialHeightInitiator to itself. It won't do this if IsPrematureSpecialHeightReflow()
1.1733 + * returns true because in that case another special height reflow will be coming along with the
1.1734 + * containing table as the mSpecialHeightInitiator. It is only relevant to do the reflow when
1.1735 + * the mSpecialHeightInitiator is the containing table, because if it is a remote ancestor, then
1.1736 + * appropriate heights will not be known.
1.1737 + *
1.1738 + * 3) Since the heights of the table, row groups, rows, and cells was determined during the pass 2
1.1739 + * reflow, they return their last desired sizes during the special height reflow. The reflow only
1.1740 + * permits percent height frames inside the cells to resize based on the cells height and that height
1.1741 + * was determined during the pass 2 reflow.
1.1742 + *
1.1743 + * So, in the case of deeply nested tables, all of the tables that were told to initiate a special
1.1744 + * reflow will do so, but if a table is already in a special reflow, it won't inititate the reflow
1.1745 + * until the current initiator is its containing table. Since these reflows are only received by
1.1746 + * frames that need them and they don't cause any rebalancing of tables, the extra overhead is minimal.
1.1747 + *
1.1748 + * The type of special reflow that occurs during printing (variety b) follows the same mechanism except
1.1749 + * that all frames will receive the reflow even if they don't really need them.
1.1750 + *
1.1751 + * Open issues with the special height reflow:
1.1752 + *
1.1753 + * 1) At some point there should be 2 kinds of special height reflows because (a) and (b) above are
1.1754 + * really quite different. This would avoid unnecessary reflows during printing.
1.1755 + * 2) When a cell contains frames whose percent heights > 100%, there is data loss (see bug 115245).
1.1756 + * However, this can also occur if a cell has a fixed height and there is no special height reflow.
1.1757 + *
1.1758 + * XXXldb Special height reflow should really be its own method, not
1.1759 + * part of nsIFrame::Reflow. It should then call nsIFrame::Reflow on
1.1760 + * the contents of the cells to do the necessary vertical resizing.

1.5573 +/* Here is the order for storing border edges in the cell map as a cell is processed. There are
1.5574 + n=colspan top and bottom border edges per cell and n=rowspan left and right border edges per cell.
1.5575 +
1.5576 + 1) On the top edge of the table, store the top edge. Never store the top edge otherwise, since
1.5577 + a bottom edge from a cell above will take care of it.
1.5578 + 2) On the left edge of the table, store the left edge. Never store the left edge othewise, since
1.5579 + a right edge from a cell to the left will take care of it.
1.5580 + 3) Store the right edge (or edges if a row span)
1.5581 + 4) Store the bottom edge (or edges if a col span)
1.5582 +
1.5583 + Since corners are computed with only an array of BCCornerInfo indexed by the number-of-cols, corner
1.5584 + calculations are somewhat complicated. Using an array with number-of-rows * number-of-col entries
1.5585 + would simplify this, but at an extra in memory cost of nearly 12 bytes per cell map entry. Collapsing
1.5586 + borders already have about an extra 8 byte per cell map entry overhead (this could be
1.5587 + reduced to 4 bytes if we are willing to not store border widths in nsTableCellFrame), Here are the
1.5588 + rules in priority order for storing cornes in the cell map as a cell is processed. top-left means the
1.5589 + left endpoint of the border edge on the top of the cell. There are n=colspan top and bottom border
1.5590 + edges per cell and n=rowspan left and right border edges per cell.
1.5591 +
1.5592 + 1) On the top edge of the table, store the top-left corner, unless on the left edge of the table.
1.5593 + Never store the top-right corner, since it will get stored as a right-top corner.
1.5594 + 2) On the left edge of the table, store the left-top corner. Never store the left-bottom corner,
1.5595 + since it will get stored as a bottom-left corner.
1.5596 + 3) Store the right-top corner if (a) it is the top right corner of the table or (b) it is not on
1.5597 + the top edge of the table. Never store the right-bottom corner since it will get stored as a
1.5598 + bottom-right corner.
1.5599 + 4) Store the bottom-right corner, if it is the bottom right corner of the table. Never store it
1.5600 + otherwise, since it will get stored as either a right-top corner by a cell below or
1.5601 + a bottom-left corner from a cell to the right.
1.5602 + 5) Store the bottom-left corner, if (a) on the bottom edge of the table or (b) if the left edge hits
1.5603 + the top side of a colspan in its interior. Never store the corner otherwise, since it will
1.5604 + get stored as a right-top corner by a cell from below.
1.5605 +
1.5606 + XXX the BC-RTL hack - The correct fix would be a rewrite as described in bug 203686.
1.5607 + In order to draw borders in rtl conditions somehow correct, the existing structure which relies
1.5608 + heavily on the assumption that the next cell sibling will be on the right side, has been modified.
1.5609 + We flip the border during painting and during style lookup. Look for tableIsLTR for places where
1.5610 + the flipping is done.
