> If you need really prettier tables you can rely on Table->Autoformat.

I felt some sort of templating mechanism would be useful for odt
tables[1]. To this end, I have pushed some changes which honors ODF-1.2
spec[2].

The attached table-template.org and table-template.odt should serve as
an illustrative example of what is possible with the odt exporter. 

Note that you need to modify automatic-styles that are in
contrib/odt/styles/OrgOdtContentTemplate.xml. (Please consult the
comments in the attached org file.)
