I can't make the font smaller – need help with table design

Hi Tobias:
I absolutely love your table plugin. The first table that I used worked great, but I’m having difficulty with this one.

It could very well be that I have too much text, I don’t know. Might have to try redesigning (any recommendations would be appreciated).

I tried using the following code to change the font size, but it’s not working. I placed it in the custom css class box:
.wp-table-reloaded-id-N td {
font-family: Tahoma;
font-size: 10px;
color: #ff0000;
}

Can you help me please. Here’s a link to my page:

Thanks.
