Thanks Jean, this solved my preview problem.

I still have another problem is that gnumeric always use firefox as
web browser, eg. click the help / gnumeric on the web.  I have have
firefox installed, but I would like to use w3m as web browser. I
already export $BROWSER in ~/.profile
export BROWSER="/usr/bin/x-terminal-emulator -e /usr/bin/www-browser"
and www-browser is configured to link to /usr/bin/w3m. However
gnumeric seems ignore BROWSER envirnoment variable. So what should I
do?
