--- Comment #6 from Dirk Dittert <dirk.ditt...@googlemail.com> --- I have seen this behavior with POI-3.9 as well. Updating to POI-3.10 has resolved this issue for me. The columns are not hidden but just have no width. The trick is to select all columns and then choose Show (last entry of context menu) to make them visible again. -- 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
