Key Takeaways
Stop building custom tables. AG Grid ships with everything - virtualization, filtering, grouping, export, and inline editing - and it's free. The community edition alone covers most of what teams spend months building from scratch.
Custom cell editors follow one pattern: build a React component, expose getValue() via useImperativeHandle, pass it as cellEditor. That's the whole thing. The rest is just React.
Custom sorting is a comparator function with two values in and a number out. Sounds trivial. In practice, it solves sorting problems that alphabetical and numeric ordering can never handle correctly for domain-specific data.
I want to say something upfront that might sound obvious but apparently isn't, because I keep seeing teams do the opposite.
