Hi all,
I have some questions pertaining to orgtbl-mode. I am really
excited
about using it to compose all my LaTeX tables, and in fact learned
Emacs
and Org specifically for this purpose (well, I also learned them for
all
the other awesome features of Org-mode.
First of all, I was wondering how I could add vertical bars to a
table (so instead of \begin{tabular}{rrr}, something like
\begin{tabular}{r|rr} is generated when C-c C-c is executed in an
orgtbl-mode remote table). Is this possible?
Yes. The way to do this is that you write the header of the table
yourself, outside of the receive area, and then you then use
the :splice option in the "ORGTBL: SEND" line. There is even an
example in the manual:
http://orgmode.org/manual/A-LaTeX-example.html#A-LaTeX-example
Second, I have had some problems with calculations. I have the
following format for my table:
% BEGIN RECEIVE ORGTBL test
% END RECEIVE ORGTBL test
\begin{comment}
#+ORGTBL: SEND test orgtbl-to-latex :splice nil :skip 0
| Name | Age | Height |
|-------+-----+--------|
| Bob | 34 | 2 |
| James | 23 | 1.8 |
| Fred | 64 | 1.2 |
|-------+-----+--------|
| TOTAL |<pt> | |
\end{comment}
With <pt> as the location of point. I want to sum the ages and put
them
in that cell, then sum the height and put them in the adjacent cell.
When I enter the formula :=vsum(@-II+1$2..-I-1$2) into the current
cell
and then tab to the next cell and enter :=vsum(@-II+1$3..-I-1$3), it
works great. However, this is very tedious when many columns are used!
Is there a way to enter many formulae in a row and have the column
automatically updated?
There is no way to define row formulas.
However, since you are summing in the column, all $-row references
are optional, i.e. you can write the formula as
:=vsum(@-II+1..-I-1)
or even as
:=vsum(@-II..-I)
Since this is the same expression for all columns, you can copy it
into the kill ring and then move with
C-y TAB C-y TAB .....
pretty quickly through the row where you want the formulas.
