I want to shift my table slightly to the left of the page (exceeding left textwidth boundary). After many googles I however keep having trouble and can't manage to get adjustwidth to work:

end{document} 

It perfectly extends the table to the right, but will not do so for the left side. It does however extend the caption to the left, but not the whole table? Does anybody know why this is? Is it perhaps because of the multitude of used packages?
