Mouseover change tr bgcolor not working in IE

Here is the page. http://iu91.com/rs/sale/

The right side listing have a mouseover & mouseout change <tr> bgcolor function.

It works fine in Safari, Chrome, and Firefox, however it doesn't work in IE.

I've tried to debug it in IE using the developer tools and I can see that the value of bgcolor has changed however the color is still white.

I think the code is correct. Maybe the problem is in the CSS. Can anyone give me a hand?

This is because of your stylesheet base.css

Check this css Style in base.css

body, div, dl, dt, dd, ul, ol, li, h1, h2, h3, h4, h5, h6, pre,
form, fieldset, input, p, blockquote, table,caption, thead ,tfoot, th, td, embed, object {
    padding:0;
    margin:0; 
    outline:0; 
    /*vertical-align:baseline;*/
    background:transparent;
    font-family:'Microsoft YaHei',Verdana,Arial,STHeiti, Georgia;
    }

Remove the tag td from this.
