Menu Transparency & Tables edit

Hello,

my website : http://gstaadairport2.fmufd.ch

I have 2 questions:

1) Is it possible to make the Sub-Menu a little transparent ? That would be nice!

2) I have Problems with Tables : http://www.pixhoster.info/f/2016-10/f4f846aeeb362c5f0c9258abb12cbb4a.png
My goal is to align all the columns, I don’t understand how it decides the size of each column. Now its looking ugly.

Thanks for your help!
