Hi,

Try this. Pass 'noofcols' as a parameter. I think the best you can do in 1.0
is calculate it once for each table and pass it to each template that needs
it.
In 2.0, tunnel parameters allow you to declare the parameter only where you
need the value.

I also made a few changes to define attribute values better and produce valid
html.
