[Orgmode] date functions in org tables

[Thorsten]

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
