Configures the header filter feature.
A header filter allows a user to filter values in an individual column by including/excluding them in/from the applied filter. A click on a header filter icon invokes a popup menu with all unique values in the column. By selecting or clearing the selection of values in this menu, the user includes/excludes them in/from the filter.
To make header filter icons visible, assign true to the headerFilter.visible option.
A header filter's popup menu lists all column values. If they are numbers or dates, you can group them using the groupInterval option in the column's headerFilter. You can also provide a custom data source for a header filter using the dataSource option. View Demo
