I use Lyx Version 2.0.2 on mint (13) mate 64 bit.I needed some very long time to figure out, why the rotation of the cell (in the first column) and the TeX-Code (in column 2+3) does not work.
At least I found, that this is a problem of DVI. Displaying the Document with DVI-Latex works correct!
May be knowing this will prevent some users wasting lots of time looking for he bug in their document.
