Analytical chemistry in React

Molarity, ppb and dose types, with a contaminated batch the rules find

type: molarity · ppb · doseRate

This is an analytical chemistry sheet with molarity, parts-per-billion and dose-rate types, and a contaminated batch that the rules find. It shows domain units and inline rules catching a real problem in scientific data.

Loading a live grid…

This is the React version. The grid mounts through the createLatticeGrid adapter, which takes its configuration as ordinary props and hands back the live grid through a ref. The grid below is the same one every other tab runs.
