[O] Elementwise division of two columns in table
Given a table of the form | a | b | c | |[2,3] | [4,6] | formula What is the formula for column C such that elementwise division is performed to obtain [2,2]. I realize I've to use the (calc-map OPR) function but I am not an expert in elisp. Thanks for reading. Regards, Nishan -- Nishan Singh Mann

Thanks for taking the time to put your (and my!) thoughts into words. If Github is indeed the sticking point, why can't it (the htmlize repo) be cloned on the same server as org-mode (possibly as its own repo, possibly as a git submodule)? It's not a fast moving target: a handful or two of commits per year. The doc can then avoid the Gihub ref (although it does seem silly to pretend that Github does not exist). -- Nick "There are only two hard problems in computer science: cache invalidation, naming things, and off-by-one errors." -Martin Fowler

Re: [O] Latex export with \begin{equation}
Oh thanks,
I thought it would be good to add a comment to the Org mode manual although it
is of course not really Org mode related.
I decided that a good location would be
https://orgmode.org/manual/Math-formatting-in-HTML-export.html#Math-formatting-in-HTML-export
A proposed patch is attached, please let me know what you think.
Best,
Dominik

so I found the reason. Both Org versions behave the same, sorry for the
confusion. The original equation that does not get exported correctly
contained
angles:
\begin{equation}
= \frac{\sum_i w_i k_{eff}(i)}{\sum_i w_i}.
\end{equation}
This equation is correctly rendered when using a .tex file and native LaTeX.
If the angles are removed, the Org Mode HTML export works:
\begin{equation}
k_{eff} = \frac{\sum_i w_i k_{eff}(i)}{\sum_i w_i}.
\end{equation}
Does anybody know why? Is this expected behavior? Can this be changed?
Maybe this explains it:
"...Also, since the mathematics is initially given as text on the
page, you need to be careful that your mathematics doesn’t look like
HTML tags to the browser (which parses the page before MathJax gets to
see it). In particular, that means that you have to be careful about
things like less-than and greater-than signs (< and >), and ampersands
(&), which have special meaning to the browsers. For example,

I know there is an package called ox-freemind. It can export Org to mindmap. The really awesome is real-time synchronize visualization Org and Mindmap program.
