示例1: styleDidChange
void LayoutTableCol::styleDidChange(StyleDifference diff, const ComputedStyle* oldStyle)
{
LayoutBox::styleDidChange(diff, oldStyle);
// If border was changed, notify table.
if (parent()) {
LayoutTable* table = this->table();

table->invalidateCollapsedBorders();
} else if (oldStyle && oldStyle->logicalWidth() != style()->logicalWidth()) {
// FIXME : setPreferredLogicalWidthsDirty is done for all cells as of now.
// Need to find a better way so that only the cells which are changed by
// the col width should have preferred logical widths recomputed.
for (LayoutObject* child = table->children()->firstChild(); child; child = child->nextSibling()) {
if (!child->isTableSection())
continue;

}
}
}
}示例2: willChangeTableLayout
void TableLayoutAlgorithmFixed::willChangeTableLayout()
{
// When switching table layout algorithm, we need to dirty the preferred
// logical widths as we cleared the bits without computing them.
// (see calcWidthArray above.) This optimization is preferred to always
// computing the logical widths we never intended to use.
m_table->recalcSectionsIfNeeded();
for (LayoutTableSection* section = m_table->topNonEmptySection(); section; section = m_table->sectionBelow(section)) {
for (unsigned i = 0; i < section->numRows(); i++) {

if (!row)
continue;
for (LayoutTableCell* cell = row->firstCell(); cell; cell = cell->nextCell())
cell->setPreferredLogicalWidthsDirty();
}
