I am very upset! Following Libre’s instructions, I uninstalled OpenOffice before installing Libre 4.0, but when using Libre to open an OpenOffice doc, the table format was gone. How can I to get the table formatting back?
You should have warned this would happen!
It is impossible to warn on all of the bugs that are present in product. Some of them may not even been known as bugs. I suggest to report a bug (from LibreOffice menu Help | Send Feedback). And if OpenOffice works for you, you will probably need to reinstall it back until bug is fixed.
