Release Release v0.6.0 · streamlit/streamlit-pivot-table

🎈 Version `0.6.0`

Release date: August 26, 2026

pip install --upgrade streamlit-pivot

Custom member grouping lets you roll raw dimension values into named groups — territories, product bundles, ad-hoc segments — from Python or from the header menu.
collapse_row_groups=True starts hierarchy (and table-with-subtotals) views collapsed, the same as Collapse All in the toolbar.
suppress_warnings=True hides informational banners (virtualization, hybrid execution reason, compute time) while still recording them in perf_metrics.
Virtualized tables keep header, body, and Grand Total columns aligned, size the row-header column from its labels, and ellipsize overflow instead of painting into the next column.
Hybrid mode caches aggregation results across display-only reruns so changing layout or warnings does not re-aggregate.

New member_groups parameter combines one or more raw dimension members into a named group shown in the pivot instead of the individual members.
In interactive mode, each dimension header menu exposes Create Groups / Edit Groups. Active groups appear as FilterBar chips and in the Settings Panel, with per-group remove and per-field clear.
New collapse_row_groups parameter (bool, default False) folds all collapsible row groups on first load. Users can expand interactively; persisted state is restored on reruns. No effect with fewer than two row dimensions, or when groups are not collapsible (show_subtotals=False and row_layout is not "hierarchy").
Expand and collapse now move one level at a time. Collapsing a parent records the levels beneath it, so expanding it reveals the next level rather than the whole subtree. Collapse All and collapse_row_groups share that rule.
The hierarchy row-header column is resizable, matching table layout.

Member groups are applied before aggregation, so subtotals and totals reflect the grouped members.
Changing member_groups invalidates the sidecar cache and triggers a server re-aggregate in threshold_hybrid mode.
Groups cannot nest (a group name cannot be a member of another group).

New suppress_warnings parameter (bool, default False) hides informational warning banners inside the component. Banners that mean the table is showing incomplete data — row truncation and column-cardinality cap — are always shown. Warning text remains in result["perf_metrics"]["warnings"].
Virtualized tables use a shared colgroup width contract across header, body, and totals so columns stay aligned above the 5,000-cell DOM budget.
Column windowing is reserved for tables with more than 200 columns, avoiding stretched columns on typical wide-but-not-huge pivots.
Column resize starts from the declared width rather than the stretched on-screen measurement.
The row-header column is sized from its dimension names and labels (capped) so hierarchy breadcrumbs and city names are not crushed into 120px by default.
Row-header labels that still do not fit ellipsize; the full text is available on hover.

Aggregation results in threshold_hybrid mode are memoized across display-only reruns.
Member-group application was optimized, with updated performance baselines.
Automated coverage was expanded for grouping, collapse/expand, virtualized column alignment, and warning suppression.
