    Get mouse hover effect work on tables create by twiki

    Hi guys,

    I am having a problem of getting mouseover event work on a webpage which is pre-populated by a third party tool twiki. The html code is something like this:

    HTML Code:
    <table cellspacing="0" id="table1" cellpadding="0" class="twikiTable" rules="rows" border="1"> 
    		<tr class="twikiTableOdd twikiTableRowdataBgSorted0 twikiTableRowdataBg0"> 
    On the condition of knowing what the table name (always going to be table1) will be, can I write some javascripts to make the mouse hover effect work.

    Here is the code I use but I can't get it work somehow.

    HTML Code:
    <!-- highlight --> <style type="text/css"> 
    tr:hover, tr.highlight { background-color: #aaa; } 
    function setupHighlight() {
        var rows = document.getElementsByTagName('tr');
        alert("rows is: " + rows);
    	for (i = 0; i < rows.length; i++) {
            rows[i].onmouseover = highlight;
            rows[i].onmouseout = dehighlight;
    function highlight() {
        this.className = "highlight";
    function dehighlight() {
        this.className = "";
    Please can you shed some lights on it? Much appreciated.

    Best regards,

    twikiTableOdd:hover, twikiTableEven:hover {
        background-color: #aaa !important;
    Forget the javascript. Just use the !important keyword there and it will over write the properties no matter where it's found in the code.
