问题 I am using Excel 2007 and it supports 1,048,576 rows but through my code it displays only 65,536 rows. If data is more than 65,536 rows I am getting the exception as Invalid row number (65,536) outside allowable range (0..65535). I used HSSF API.how to display data more than 65,536 rows in Excel sheet with HSSF API only. 回答1: Even though you are using Excel 2007, you will be limited to 65K rows, as you write to xls file using HSSF. You should be using XSSF api, to take advantage of xlsx 1M

问题 I am adding a picture into a cell using Apache POI-HSSF. The image is 120x100 but no matter what I do and how I resize it, the Excel spreadsheet always shows it spanning multiple rows and distorts it to a much bigger height than width.

My code: InputStream is = new FileInputStream(getImageURL()); byte[] bytes = IOUtils.toByteArray(is); int pictureIdx = wb.addPicture(bytes, Workbook.PICTURE_TYPE_JPEG); is.close(); //add a picture shape CreationHelper helper =

Which library should I use to write an XLS from Linux / Python?

由 不问归期 提交于 2019-12-09 06:05:46
问题 I'd love a good native Python library to write XLS, but it doesn't seem to exist. Happily, Jython does. So I'm trying to decide between jexcelapi and Apache HSSF: http://www.andykhan.com/jexcelapi/tutorial.html#writing http://poi.apache.org/hssf/quick-guide.html (I can't use COM automation because I'm not on Windows, and even if I was, I couldn't afford Office licenses.) My initial thoughts are that POI/HSSF is very thorough, but also very Java-- everything seems a bit harder than it needs to
