On German discuss-ML the following bug has been reported. I quote: "Using LibreOffice 3.4.0 (Build: 12) and OpenOffice 3.2.0 (Build: 9483) on Ubuntu 10.04LTS, I found a bug, rendering tables in writer. Every Time I use double lines as header seperator, weird things happened, if the document is opened in the opposing writer. So that double line (0,25pt with the wider gap) first created in openoffice, has the strange effect of beeing thicker and the bottom line in a two row table looks as if not 1pt wide (as I created it in openoffice and will sometimes not been printed!). When having a tables with at least three rows the double line remains strange looking and the bottom line is ok. If a simple double line (0,25 with normal gap) is created in LibreOffice, the document in OpenOffice will not show it at all. Maybe your Line-IDs in the ODS-Format are a little bit mixed up."
