Need a style in maincss.css for form widget use

[Leon Torres]

Hi, we need a style in maincss.css for form widget tables to give them 100% 
width style with a 1px border.  Basically we need to make the table the size of 
the page, otherwise the columns will be squished together.  Adding a 1px border 
is also a good cosmetic effect.

I found that the class .boxoutside is suitable for this if "width: 100%" is 
added.  Alternatively, a new style could be created by copying boxoutside and 
adding the width 100%.

What would be the best way?
