I am playing with SharePoint 2010 and PowerPivot and in the demo’s from MS the PowerPivot sheet don’t look like excel. I was wondering how they did that and started looking for it. But I couldn’t find it, then i remembered Rob showed it to us on his blog post . It’s pretty easy:
Go to view, and deselect Gridlines and Headings and give your sheet a background color:
Makes you sheet look a lot better !
