Hi.
Is there any way to somehow mark cells in an org-table and then sum
over all marked cells of the whole table. For example in the following
table I marked some time values bold:
| | Col 1 | Col 2 | Col 3 | Col4 | Sum |
|--------+-------+--------+--------+------+----------|
| Row 1 | | *1:00* | | | 01:00:00 |
| Row 2 | 8:30 | 6:30 | *7:00* | | 22:00:00 |
|--------+-------+--------+--------+------+----------|
| Sum | | | | | 23:00:00 |
| Marked | | | | | 08:00:00 |
#+TBLFM: @>$>=??????::@>>$>=vsum(@<<..@>>>);T::$>=vsum($<<..$>>);T
Exist some clever trick to be used as formula for @>$> or is a custom
lisp function needed for this?

Until the next mail...,
Stefan.

For numbers instead of times yes, there is often fun with complex
numbers:
| | Col 1 | Col 2 | Col 3 | Col4 | Sum |
| | <r> | <r> | <r> | <r> | |
|--------+-------+---------+---------+------+------|
| Row 1 | | i * 1.0 | | | 1.0 |
| Row 2 | 8.5 | 6.5 | i * 7.0 | | 22.0 |
|--------+-------+---------+---------+------+------|
| Sum | | | | | 23.0 |
| Marked | | | | | 8.0 |
#+TBLFM: $> = re(vsum($<<..$>>)) + im(vsum($<<..$>>)) +.0; f-1 ::
@>>$> = vsum(@<<<..@>>>); f-1 :: @>$> = im(vsum(@<<<$<<..@>>>$>>))
+.0; f-1
The marked fields can be highlighted with hi-lock-mode.
Unfortunately it does not work with time format because the Org time
format parser reasonably does not deal with a Calc expression in a
field but "only" with a pure time.
For "+.0" and "f-1" see
http://orgmode.org/worg/org-faq.html#table-float-fraction

For time calculation I would say yes and to use Org emphasis as you
suggest with bold seems a good idea. A custom function would be
necessary not only for @>$> but also for the other formulas because
Org does not omit emphasis when parsing the fields (which would be a
nice feature, maybe always or only together with some new format
specifier).
