Filter column headers
Functionality request: Would it be possible please to consider enable filtering on the column header? Meaning, if you would hover over the header, a drop-down would appear and you could either select value(s) in the rows or enter free text. Analog to the filter functionality in excel.

I believe it is the same as your request (correct me if not, and I will open another discussion for it, unless someone like @dstillman point me to another discussion with this request).
