话不多说，贴上代码
html代码：
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <link rel="stylesheet" type="text/css" href="../extjs3/resources/css/ext-all.css" rel="external nofollow" /> <script type="text/javascript" src="../extjs3/adapter/ext/ext-base.js"></script> <script type="text/javascript" src="../extjs3/ext-all.js"></script> <script type="text/javascript" src="array-grid.js"></script> <style type="text/css"> .<span style="font-family: Arial, Helvetica, sans-serif;">my_row_class</span><span style="font-family: Arial, Helvetica, sans-serif;">{ background:gray;}</span> </style> </head> <body> <div id="grid-example"></div> </body> </html>js代码,其中应-----隔开的代码即为关键代码，自己分析吧：
