Bug 9012 – Row height not updated when cell heights change

• Status: RESOLVED
• Resolution: FIXED
• Component: Tables

Grid row heights are initially increased as dictated by cells in the row (in RenderTableSection::addCell), but later changes to cell heights are not reflected in the grid. (Once bug 3297 is fixed, this becomes more apparent since it starts affecting rows other than the first row).

To reproduce: open the attached test case and click the Test button. After you click, the tables should be identical, but the table on the left maintains a taller first row due to this bug.

Patch w/test and change log

tables/mozilla_expected_failures/bugs/bug222846.html no longer fails with this patch, so perhaps it should be moved to mozilla (I don't know how to represent a move in a patch).

Shouldn't this:

+    if (parent() && section() && (!style() || style()->height() != newStyle->height()))
+        section()->setNeedCellRecalc();

be:

(style() && style()->height() != newStyle->height())

?

Doesn't seem like you need to call setNeedCellRecalc on a section when you don't even have a style() set yet.  (The act of just adding the cell to the DOM in the first place already took care of that case I think.)
