This code was heavily copied from http://www.kryogenix.org/code/browser/sorttable/.
It requires the Prototype.js library available from http://prototype.conio.net/ (the version included on this site is from the script.aculo.us distribution).

New features:

• User specified "arrow" text (because innerHTML is used to set the text, it should be possible to specify an <img> tag for the arrow text)
• Uses HTML TFOOT element to identify footer (as opposed to a special class)
• Can specify alternating row classes (e.g. so every two or three rows is a different color)
• Because the arrows are hidden instead of replaced with spaces, columns won't shrink/expand when sorting
• Supports heterogeneous column types
• Optionally uses the Natural Order algorithm to compare text (still converts purely numeric values to floats for comparison)
• No more <a> links in the headers--I can't stand those #'s appearing in the URL
• Supports the newest Prototype.js library that breaks the symantics of the Array.reverse() method
• Other small fixes and improvements (see comments in .js file)
