This question already has an answer here:

How can I create a default table style, which remains throughout the course of my document, lets say, for example, I want grid-lines and a gray shading behind the header-row, without having to explicitly format every table instance to this standard, is it possible to define these styling flavors in the preamble to affect all tables, in effect, on a global basis?

  • The pgfplotstable package can do this. – Qrrbrbirlbel May 14 '13 at 0:11

    The first linked question in the Related section is really related: How to separate table content and table style – Qrrbrbirlbel May 14 '13 at 1:02
  • To ADP: could we close this as a duplicate of @Qrrbrbirlbel link- there's a few different solutions, one of which uses pgfplotstable package with complete MWEs.... let us know if it is different, and if so, it might be nice to elaborate a little :) – cmhughes May 14 '13 at 21:23
  • Just close it off, Qrrbrbirbel's like is what I had in mind. – Nicholas Hamilton May 14 '13 at 21:47

Try the package cals. I wrote it with a similar need in mind.
