Hello,
I have a problem with the calculation of time durations in tables.
I hope someone can help me.
*How to calculate a vector (list) of time durations in tables?*
Subtraction of numerical vectors works directly:
```
| day | t1 | t2 | differences |
|------------------+----------+----------+-------------|
| [2021-04-08 Thu] | [10, 13] | [16, 18] | [6, 5] |
#+TBLFM: $4=$3-$2
```
Using this with time vectors to compute durations) doesn't work.
It computes only the first item:
````
| day | time 1 | time 2 | durations |
|------------------+----------------+----------------+-----------|
| [2021-04-08 Thu] | [10:45, 14:00] | [12:00, 15:00] | 01:15 |
#+TBLFM: $4=$3-$2;U
````
I would expect this:
````
| day | time 1 | time 2 |
durations |
|------------------+----------------+----------------+---------------|
| [2021-04-08 Thu] | [10:45, 14:00] | [12:00, 15:00] | [01:15,
1:00] |
````
I hope there is an (easy) solution (?)
Best Regards
Frank
