--- Comment #4 from Javen O'Neal <one...@apache.org> --- It would probably be faster for us to read the merged regions into a java List and discard the CTMergedRegions, operate on the Java List, and then recreate the CTMergedRegions XML nodes when writing the workbook. Not sure whether this would improve the speed here, but I'm guessing worksheet.getMergeCells() and ctMergeCells.addNewMergeCell() are expensive calls since it's creating and linking XML nodes in a DOM. This work could be deferred to when the workbook is written out. -- 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
