I've used AG Grid at many of my companies and found it worth the price. I've also dabbled in Perspective (https://github.com/finos/perspective https://github.com/finos/perspective), but it may be overkill for you. It was a fun project similar to SQL Workbench where data can be uploaded and consumed from a specific IWMS API for client-side analysis. It's quite powerful and open source.
