Hi,
thanks for your post, and sorry for the trouble.
From what I can see, you will simply have to “force-reload” the page, e.g. by hitting Shift+F5 to reload the page. This should clear the browser cache. This is necessary on your site, because something (I think the theme) is turning off WordPress’ automatic mechanism for this.
The CSS code that you inserted will then affect table 1. I would however recommend using a dark text color, as you’ll not be able to read white text on light backgrounds. Thus, use e.g.
color: #333333;
To add CSS for other tables, just append that in the “Custom CSS” textarea, with the corresponding table IDs in the CSS.
Regards,
Tobias
