In a question I recently asked (How to make table with rotated table headers in LaTeX) the accepted answer used some features of tabular column types that I was not familiar with, e.g.,

\begin{tabular}{@{} cl*{10}c @{}}

I tried Googling for latex "@{}" but that just brought up some generic LaTeX pages.

Where can I got to learn about @{} tabular columns and other options?

Okay, so I found the answer in appendix C.10 of Lamport's book, but I'd like to know where to look for electronic resources.

The array package documentation (texdoc array on some systems) documents the original array column types as well as the additional ones added by that package. See table 1 on page 2.

That table is great. Easily found, near the beginning of the file. – jlconlin Feb 20 '13 at 14:53
