// alternating colored rows JavaScript Document
//
// remember to define a default color on the table rows via CSS
// for users with javascript turned off
//
// function sets className of even- and odd-numbered rows in a table
//
//    usage: body onload="altrows('<classname>');"
//    CSS definition: 
//       table.<classname> tr.odd {
//             background-color: <odd row color>;
//       }
//       table.<classname> tr.even {
//             background-color: <even row color>;
//       }

// mw combined script from an alternating rows script by id by rjw, and 
// one by w0lverine on forums.devarticles.com -
