This used to be known as pass 1 reflow. + * + * After the intrinsic isize calculation, the table determines the + * column widths using BalanceColumnISizes() and + * then reflows each child again with a constrained avail isize. This reflow is + * referred to as the pass 2 reflow. + * + * A special bsize reflow (pass 3 reflow) can occur during an initial or resize + * reflow if (a) a row group, row, cell, or a frame inside a cell has a percent + * bsize but no computed bsize or (b) in paginated mode, a table has a bsize. + * (a) supports percent nested tables contained inside cells whose bsizes 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 + * bsize 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 bsize but no computed bsize by calling + * CheckRequestSpecialBSizeReflow(). This method calls + * RequestSpecialBSizeReflow() which calls SetNeedSpecialReflow() on its + * ancestors until it reaches the containing table and calls + * SetNeedToInitiateSpecialReflow() on it. For percent bsize frames inside + * cells, during DidReflow(), the cell's NotifyPercentBSize() is called + * (the cell is the reflow input's mPercentBSizeObserver in this case). + * NotifyPercentBSize() calls RequestSpecialBSizeReflow(). + * + * XXX (jfkthame) This comment appears to be out of date; it refers to + * methods/flags that are no longer present in the code. + * + * 2) After the pass 2 reflow, if the table's NeedToInitiateSpecialReflow(true) + * was called, it will do the special bsize reflow, setting the reflow + * input's mFlags.mSpecialBSizeReflow to true and mSpecialHeightInitiator to + * itself. It won't do this if IsPrematureSpecialHeightReflow() returns true + * because in that case another special bsize 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 + * bsizes will not be known. + * + * 3) Since the bsizes of the table, row groups, rows, and cells was determined + * during the pass 2 reflow, they return their last desired sizes during the + * special bsize reflow. The reflow only permits percent bsize frames inside + * the cells to resize based on the cells bsize and that bsize 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 bsize reflow: + * + * 1) At some point there should be 2 kinds of special bsize 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 bsizes > 100%, there is data + * loss (see bug 115245). However, this can also occur if a cell has a fixed + * bsize and there is no special bsize reflow. + * + * XXXldb Special bsize reflow should really be its own method, not + * part of nsIFrame::Reflow. It should then call nsIFrame::Reflow on + * the contents of the cells to do the necessary block-axis resizing. + * + ******************************************************************************************/ + +/* Layout the entire inner table. */ +void nsTableFrame::Reflow(nsPresContext* aPresContext, + ReflowOutput& aDesiredSize, + const ReflowInput& aReflowInput, + nsReflowStatus& aStatus) { + MarkInReflow(); + DO_GLOBAL_REFLOW_COUNT("nsTableFrame"); + DISPLAY_REFLOW(aPresContext, this, aReflowInput, aDesiredSize, aStatus); + MOZ_ASSERT(aStatus.IsEmpty(), "Caller should pass a fresh reflow status!"); + MOZ_ASSERT(!HasAnyStateBits(NS_FRAME_OUT_OF_FLOW), + "The nsTableWrapperFrame should be the out-of-flow if needed"); + + const WritingMode wm = aReflowInput.GetWritingMode(); + MOZ_ASSERT(aReflowInput.ComputedLogicalMargin(wm).IsAllZero(), + "Only nsTableWrapperFrame can have margins!"); + + bool isPaginated = aPresContext->IsPaginated(); + + if (!GetPrevInFlow() && !mTableLayoutStrategy) { + NS_ERROR("strategy should have been created in Init"); + return; + } + + // see if collapsing borders need to be calculated + if (!GetPrevInFlow() && IsBorderCollapse() && NeedToCalcBCBorders()) { + CalcBCBorders(); + } + + // Check for an overflow list, and append any row group frames being pushed + MoveOverflowToChildList(); + + bool haveDesiredBSize = false; + SetHaveReflowedColGroups(false); + + // Bug 1863421: We need to call ApplySkipSides() for borderPadding so that it + // is correct in a table continuation. + LogicalMargin borderPadding = aReflowInput.ComputedLogicalBorderPadding(wm); + + // The tentative width is the width we assumed for the table when the child + // frames were positioned (which only matters in vertical-rl mode, because + // they're positioned relative to the right-hand edge).
