You get the preview "for free" if we set up conversion all the way
from .gnumeric to .eps (via .tex).

Just tried, but doesn't work. I patched lib/configure.py as in the
attachment, where the converter is the attached script. When
I use "Insert->graphics...", and I specify a ".gn" file, it crashes.

(of course I'm in an attempt to build-up something usable for the
very next papers I'm going to write, waiting for LyX 1.6.+ with
some Insert-support for such things).

I was thinking of only converting to .tex, and have LyX include
the generated .tex file directly. This has several advantages:

Perfectly agree. This is absolutely the way to do it.

   T.

* gnumeric exports the spreadsheet as a longtable. If you make
  a .eps, then this is limited to a single page. And you'll get
  one big figure that cannot be broken across pages. (This is
  sometimes a problem when there are more figures than text).

  A longtable imported as .tex have no such problems. It can
  start anywhere on the page because it will be broken, and
  it can go on for many pages - again because it supports
  page breaking.

* Importing gnumeric as a longtable means that style choices in
  LyX (font etc.) can affect the longtable layout. Using eps means
  LyX cannot affect the output in any way.

* Finally, longtables work equally well with all the latex exporters,
  i.e. both latex and pdflatex.


converter for previewing.

"No automatic preview" seems to be the only disadvantage of importing .tex Now, of course a preview is possible anyway because we can specify a different
