ZK Spreadsheet can filter the data to find a subset of data in a range.

Purpose

The filtered data is displayed in rows that meet the provided criteria, and hide those trivial ones.

AutoFilter

Use Range.autoFilter() to toggle AutoFilter for sheet in a range. After applying AutoFilter, users can specify criteria by calling Range.autoFilter(integer, object, integer, object, boolean) to filter data in a range.

Reapply filter

If the content within AutoFilter range has been added, modified or deleted, reapply the current filter can force the sheet to update the result per the current filter criteria. Use Range.applyFilter() to reapply the current filter.

Clear filter

Use Range.showAllData() to clear the current AutoFilter.
