Sort and filter tables

This should also include the ability to sort by multiple columns (just like in Excel)

Yes, I agree. Ability to filter Matrix columns supplied by small icon at each column header is desireable.

And it would be convenient if tables could also be filtered (for viewing) in data view - just like in PowerPivot, (not only in query editor). Maybe this needs a separate entry.

This would be awsome to have. Redusing the need for Slicers on the report page

Filter in Column header would be very useful, please implement it

This is single most important feature that is preventing people from fully using our Power BI Reports. First thing everyone asks for is .. how can I export because Excel gives them that easily ability to filter columns which are for a lot of cases a key way to analyze data. Dropdown slicers are great but only so many one can add and they take up a whole lot of space too. Please implement this!
