Grid/Table Option in Layouts

It would be great to have a grid or table cell layout so that pictures or documents can be perfectly aligned on a page. This is because the snap to grid option doesn't always line up properly, and getting sizing even is very fiddly. Each cell should be able to be assigned "media" or a "document" etc. The cells should be able to be set to have fit, stretch etc. Borders should be changeable, i.e thickness and colour - they should also have options to have a thicker outside border
