This is the official manual for the latest Org-mode release.
Radio tables are target locations for translated tables that are not near their source. Org finds the target location and inserts the translated table.
The key to finding the target location are the magic words
RECEIVE ORGTBL. They have to appear as comments in the current mode. If
the mode is C, then:
/* BEGIN RECEIVE ORGTBL table_name */ /* END RECEIVE ORGTBL table_name */
At the location of source, Org needs a special line to direct Orgtbl to translate and to find the target for inserting the translated table. For example:
#+ORGTBL: SEND table_name translation_function arguments...
table_name is the table's reference name, which is also used in the
receiver lines, and the
translation_function is the Lisp function that
translates. This line, in addition, may also contain alternating key and
value arguments at the end. The translation function gets these values as a
property list. A few standard parameters are already recognized and acted
upon before the translation function is called:
:skipcols (n1 n2 ...)
To keep the source table intact in the buffer without being disturbed when the source file is compiled or otherwise being worked on, use one of these strategies:
