I don't remember looking at Glide, although it looks really nice & full-featured. I'll have to play around with it sometime. I do remember trying out https://www.npmjs.com/package/@deephaven/grid.

One pivotal feature that is difficult to map onto 3P tools is our data table UI, which is a separate scrollable grid that floats on top of the main sheet. That, combined with the complexity of formula selection, inserting buttons into cells (header dropdowns, filter, sort), led us to decide that rolling our own solution for full control was the right choice.
