Question

I use the following attributes for create the Table. I use the cellSpacing="5" for space. When I execute the whitespace will appear fine inbetween the cells in the Table. How to change the cellspacing whitespace on mouse over event with another color? Is This Possible?

Table Creation:

    <table border="0" id="TabDeclaration"  width="100%" cellpadding="5" cellspacing="3" border="2">
        <tr>
            <td>aaaa</td>
            <td>bbbb</td>
            <td>azaz</td>
        </tr>
        <tr>
            <td>cccc</td>
            <td>dddd</td>
        </tr>
        <tr>
            <td>eeee</td>
            <td>ffff</td>
        </tr>      
    </table>

You could use the following to change the background-color on hover:

<script>
    $(function() {
        $('td').hover(function() {
           $(this).addClass('hover');
        }, function() {
           $(this).removeClass('hover');        
        });
    });
</script>

<style>
    td {
        background-color: red;        
    }

    td.hover {
        background-color: blue;        
    }
</style>
