I assume you mean xslt 1.

That depends of course what the previous experience of the coder is.
variables in declarative languages denote values rather than memory
locations, so they act in a natural way so long as you use variable with
its normal meaning rather than the somewat strained use of the term in
imperative programming languages where strange things like x=x+1 make
sense.

You want the sum of all the colspan attributes that have a numeric
attribute plus the number of th elements without such an attribute

select="
  sum(th/@colspan[number(.)=number(.)])
   +
  count(th[not(@colspan) or not(@colspan[number(.)=number(.)])])
  "
