Fwd: long horizontal table over two pages

[Wolfgang Engelmann]

Hi,

I have a in a koma script book a long horizontal table and would like 
therefore to get its output on two facing pages. I couldn't find a way 
to do it in the embedded objects help document, or I have overseen it. 
Is there a way to do it in lyx (or ERT?).
As an alternative I could use numbers for the references used in the 
table (in two columns), but the general citation uses names. Any trick 
to do it? Perhaps with footnotes?
I use LyX Version 2.4.0dev (not released yet)
