These tables are generated using a python script which extracts the data from Matlab files. To write every caption or heading only once I use a data file in which I store key:value-pairs.
# comment key-1: this is the snippet which reoccurs often. key-2: and this is another one
To highlight the keys and the comments I use generic-mode (see in Emacswiki).
To enable this I added:
# -*- mode:chunkdata -*-
in the first line of the data-file. Now all Comments are highlighted in dark-red and all keys in dark-yellow. The result is a much better readability.
