The interface for implementing Filters on SpreadsheetColumn. Simply set a Filtered row on the SpreadsheetView by using SpreadsheetView.setFilteredRow(java.lang.Integer).

A Filter is simply a customizable MenuButton that will be displayed over the cell. It is primarily designed to filter some rows in the SpreadsheetView. But the MenuButton can serve any purpose since it is entirely customizable.
