multirows in tables

[Uwe Stöhr]

Hello everybody,
I'll write a table with a multirow like these:

AAAAA | BCDEF | GHIJK
----------------------------
           | Blaa1  | Blaa1
BBBBB  |------------------
           | Blaa2  | Blaa 2
----------------------------
CCCCC | BCDEF | GHIJK

But I'm not able to put the entry BBBBB in the middle of two rows. LyX offers only a 
position in the first row or in the second and tells me that multirows are not 
possible at the moment.

So when will it be possible? And is there another solution for doing this?

Thanks Uwe
