Reported symptom: with split_rollup_mode on, columns looked shuffled and some month columns had no year header above them. That was this spike, not Perspective. Two mistakes, either enough on its own: - The original span was stashed on the cell as `_pfFullSpan` the first time it was seen. regular-table recycles header cells between draws, so the stashed value reappeared on an unrelated group and truncated it. - The work was guarded on `colSpan > 1`, so once a cell had been set to 1 it could never grow back. Both fired even with nothing collapsed, which is why merely turning rollup on was enough to break the header. Now the span is derived from the column paths every draw, and colSpan is only touched while something is actually collapsed — with nothing hidden, regular-table's own merge of adjacent equal header values is the right answer and is left alone. Measured on Reason x (Year, Month), 18 leaf columns, across first draw, sort, sort-cleared and horizontal scroll: before fix 2025 spans 3, group row covers 8/18 (10 orphaned) after fix 2025 spans 13, group row covers 18/18 no spike 2025 spans 13, group row covers 18/18 Collapse behaviour is unchanged: 8 -> 6 -> 3 -> 5 cells across collapse 2025, collapse 2026, expand 2025, with header and body width-aligned throughout and the state surviving a sort. Not fixed, because it is not a bug: rollup emits totals BEFORE their members, so the grand total sits far left and each year's subtotal precedes its own months. SplitRollupMode documents this as "totals before" order and offers only flat|rollup, so it cannot be moved to Excel's convention.

React + Vite
This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
Currently, two official plugins are available:
- @vitejs/plugin-react uses Oxc
- @vitejs/plugin-react-swc uses SWC
React Compiler
The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see this documentation.
Expanding the ESLint configuration
If you are developing a production application, we recommend using TypeScript with type-aware lint rules enabled. Check out the TS template for information on how to integrate TypeScript and typescript-eslint in your project.
