After reading in a source .xls file and making modifications, the new output .xls has lost the information about what rows should be repeated at the top of each printed page. I'm not sure if the columns are lost too.
I thought we supported repeating rows... in any case not a show stopper for 2.0 but should be fixed in 3.0
Try the latest POI-3.5-beta4. Repeating rows and columns are supported and should be preserved across read/write. Yegor
