Translation and some extra space in field "cart"

Where can I translate "Clear" for the signature in the Dutch language. I can't find it. It needs to be "Wissen".
And, please look at the picture, I am using the fields for e-mail notification.
Between the number of products and the price is no space. Can it be added somewhere?
Regards, Peter
