Comment 16 for bug 254655

This comment in the upstream bug, https://bugs.freedesktop.org/show_bug.cgi?id=33631#c6, says to put the table into a frame, and this seems to work (I'm currently on libreoffice-writer 1:4.3.2~rc2-0ubuntu1~trusty2).

You have to be careful to not make the frame bigger than the table, or it will overwrite the footer (even if fill type is set to none).
