Try to put data in one of the tables. Jump with tabulator. Saving data doesn't work.
When writing data direkt into a table the tabulator will move from the first to the last column and then isn't seen again. In earlier versions of LibreOffice (and OpenOffice) after the last column data is saved and tabulator sets input-cursor to the first column of the next row.
I reproduced this on master and 3.5 branch.
I proposed a patch on dev mailing list, cf http://nabble.documentfoundation.org/PATCH-proposed-fix-for-fdo-44283-td3648948.html
Looking at your patch I *guess* this is a missed change required by http://cgit.freedesktop.org/libreoffice/core/commit/?id=f7ed67f2cf79fd067c1634e8f7c3f8a17792f2e5 and looks good to me
Fixed in libreoffice-3-5 with commit de89f1694b4cb2a5bf8ade020bfdef33e7135d35 and in master (LibreOffice 3.6) with commit a3261b16471995832f6791b5831c640c72948a95.
Thanks Robert for the bug report and Julien for pointing me the the right place in the code.
