ZK Pivottable 4.0.0 Release Notes

Released on Oct 28, 2026


ZK Pivottable 4.0.0 moves Excel export to the Keikai 7 spreadsheet engine, improves exported spreadsheet behavior, and fixes a missing source code issue.

Excel export now uses Keikai 7 in place of the POI-based implementation. The update also brings several improvements to exported files: Fonts configured through export customization are now applied correctly; Grand totals disabled in the export remain disabled after refreshing the pivot table in Excel; Data sheet names containing spaces are handled correctly.

ZK Pivottable is an Ajax data component, which takes raw data from a flat table (like tables in relational database) and organize them by desired categories arranged on columns and rows. ZK Pivottable brings the power of spreadsheet's pivot table to Java web applications, enabling developers to take advantage of a readymade component for presenting complex sets of data online.
