How to set table width to autofit to 100% in table stylesheet

[ChoccieMuffin]

I've had a play with my table stylesheets and can't see how I can set my tablestyles to always be 100% (autofit to window, if you adjust an individual table's properties).

I've tried adding width: 100%; to the end of the mcTableStyle thing in the code, but that has no effect. I also have this in my regular stylesheet:
table
{
width: 100%;
}
So I don't know what else I need to do.

Suggestions very welcome - I'm playing in my global project and have managed to break ALL my tables in ALL my child projects!

More and more I've noticed that table stylesheets seem to cause problems. My only suggestion would be to try dissociating any current table styles from a test table and then ensure the topic is linked to a stylesheet with the table { width: 100%; } directive present.
