Hello,
is there something like a column formula in org that enables me to introduce a
date in the first row and then automatically fills the other rows of
that column with followup dates (+ 1 day or + 1 week i.e.)
like this:

| date            | kg |
|-----------------+----|
| <2011-02-08 Di> | 86 |
| <2011-02-09 Mi> | 85 |
|     etc.        |    |
 
thanks for any hints
cheers
Thorsten

Interactively S-<RET> will insert a row with the next date (i.e. the + 1
day bit), but I don't know of a way to make it skip by larger
steps (i.e. the + 7 days bit).

With a table formula, you can skip by as much as you want:

--8<---------------cut here---------------start------------->8---
* Consecutive dates

| Date             | Weight |
|------------------+--------|
| <2011-02-25 Fri> |     71 |
| <2011-03-04 Fri> |        |
| <2011-03-11 Fri> |        |
| <2011-03-18 Fri> |        |
| <2011-03-25 Fri> |        |
#+TBLFM: @2$1=<2011-02-25 Fri>::$1=<@-1$1>+7
--8<---------------cut here---------------end--------------->8---

using a field formula to set the first entry and a column formula
to calculate the rest, but it just fills up pre-existing rows. IOW,
if you want a bigger table, you have to insert a number of empty
rows and then recalculate.

HTH,
Nick
