Template row/column sizes not respected

[The-MAZZTer]

I should be able to specify row/column sizes in my template and not have them overridden.

In Excel if I go to View > Page Layout I can see if my spreadsheet fits on a page.

ClosedXML.Report seems to size columns/rows to fit which means a spreadsheet which should fit on 1 page is overflowing both horizontally and vertically over the page boundary. This is not acceptable in hard copy scenarios.
