Hi all,
I have two questions concerning tables in orgmode:
1. What is the best way to handle missing values?
I have the problem, that missing values ("") are treated as "0" when they
appear in a formula.
Entering ("nil") instead helps a bit, but does not propagate,
i.e. nil + 1 results in 0.
Can I do better?
2. What is the best way to drop a column while preserving the number of
digits displayed?
I use a simple code block to drop the columns. But I do not see how
to prevent orgmode from dropping trailing 0s
Here is an example demonstrating both questions:
--8<---------------cut here---------------start------------->8---
#+TITLE: Drop columns
* Create Some Table with a Missing Value
#+name: mytable
| Item | Price ($) | Price ($+1) |
|-----------+-----------+-------------|
| Apple | 10.55 | 11.55 |
| Tomato II | nil | 0.00 |
| Tomato | | 1.00 |
| Pear | 3.00 | 4.00 |
| Monkey | 100.55 | 101.55 |
|-----------+-----------+-------------|
| Sum | 10.55 | 118.10 |
#+TBLFM:
$3=$2+1;%.2f::@7$2=vsum(@address@hidden);%.2f::@7$3=vsum(@address@hidden);%.2f
* Drop a Column
#+name: mysmalltable
#+begin_src emacs-lisp :var input=mytable[,0:1] :exports results
input
#+end_src
#+results: mysmalltable
| Item | Price ($) |
|--------+-----------|
| Apple | 10.55 |
| Tomato | |
| Pear | 3.0 |
| Monkey | 100.55 |
--8<---------------cut here---------------end--------------->8---

Andreas
