1. Optional (but recommended): Buy the Excel 97 Developer's Kit by Micrsoft Press from Amazon.com (out of print, but cheap if bought used)
2. Create a blank sheet with ONLY enough data/etc to demonstrate the feature you want to implement
3. Create a blank sheet that is identical minus that feature
4. run java org.apache.poi.hssf.dev.BiffViewer MySheet.xls >output.foo on both (substituting other file names for input and redirect)
5. Run the UNIX diff command (or equivilent) on the redirected output and compare
6. Create a unit test for testing the funcitonality
7. Create a low level implmenetation (including records and appropriate changed to the model) o.a.c.p.hssf.model
8. Create high level api to manipulate the model
9. Update documentation
10. Follow the patch instructions here: http://jakarta.apache.org/poi/getinvolved/index.html
This conversation however is more appropraite for poi-dev list

Hi,
There is an option in File/Page Setup/Sheet tab/Repeat rows and repeat
columns. I need to use this option to repeat the same row in all the pages
(like a header but i have to do it this way because I need an image in my
header). How can i set this option using POI?
I`ve also tried to use a template that has this option set, but when a read
this template using POI an rewrite it in another file, i loose the option i
have set.
How can i implement this in POI?
Tnanks,
Christian
