ZK Spreadsheet Essentials/Working with ZK Spreadsheet/Configure and Control ZK Spreadsheet/Filter Data in a Range

Available in ZK Spreadsheet EE only

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

Purpose

Filtered data display rows that meet provided criteria, and hide those trivial ones.

AutoFilter

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

Reapply filter

If contents 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 current filter.

Clear filter

Use Range.showAllData() to clear current filter.
