--- Comment #12 from Axel Howind <a...@dua3.com> --- I remember observing very bad performance in handling merged cells starting in POI 3.14(?). IIRC it was not only with autoSizeColumn(), but whenever trying to query merged regions of a sheet. It could even be that it was just getNbOfMergedRegions() in XSSF that was so horribly slow. I coded around this issue. Maybe I will dig into this again when I find the time. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@poi.apache.org For additional commands, e-mail: dev-h...@poi.apache.org
