useTableTreeState @astryx-svelte/core v0.3.0 · Table

Usage

State management companion for useTableTreeData. Owns the expanded set (controlled or uncontrolled) and flattens nested data into the visible row array; collapsed subtrees are unmounted, not hidden, so the table body contains exactly the visible rows. Returns expandAll/collapseAll helpers, the aggregate isAllExpanded state (true/false/indeterminate) for a header expand-all control, and a ready-to-use config for the tree plugin. Note: because collapsed rows unmount, cell-local React state inside collapsed subtrees is lost on collapse; lift state that must survive.

Examples

Common configurations, variations, and states.
useTableTreeData: Tree Table
A file-tree table built from nested data. useTableTreeState flattens the tree into the visible rows and owns the expanded set; useTableTreeData draws the per-level indent and the expand/collapse chevron in the tree column. The two hooks are designed to work together, so this one example covers both. hasExpandAllControl adds the expand-all/collapse-all toggle to the tree column header. Collapsed branches are unmounted, not hidden.
