Created attachment 164261 [details] Test case See HTMLTableCellElement.cpp: // Clamp rowspan at 8k to match Firefox. static const int maxRowspan = 8190; The limit was bumped up on other browsers including FF and we now have the lowest limit. Not sure why the limit is kept this low the rendering code should be able to handle higher values for rowspans. I haven't tried to determine what would be a better limit and that would need to be investigated.

FF currently uses 2^16 - 2 as the max value for rowspan. This value is chosen due a limitation in there impl of cell maps. http://mxr.mozilla.org/mozilla-central/source/layout/tables/celldata.h#17
