=dsum(Timetable!A1:F45,"Time Delta",A1:A2) works, but the manual then is
a bit misleading. In example 5.10 in
http://www.gnome.org/projects/gnumeric/doc/sect-data-types.html, they
say you are to do  =SUM('Sheet 1'!A1:'Sheet 1'!A5) when referencing a range
from another sheet..

Also, why is it that "Time Delta" doesn't have a sheet scope on it? What
if I happen to have a "Time Delta" field in the Jobtable (which I don't,
but this seems like it would produce ill-defined behavior then).

Also, do I really need to use a range for the third argument? I really
don't want to have to create 16+ (the actual number of Jobs is
unbounded) mini-tables with just a "Job #" and a number in it,
especially when I already number each job in the Jobtable sheet. Is
there a function or something I can do to avoid all these needless
mini-tables?

Example 5.7 of the manual (same page) says I am supposedly able to specify
combination of cells with commas, which is again misleading cause it
doesn't work in this case.
