    I'm not clear what those useEffect groupings are, but given the table is defined in a different one to the declaration of handleButtonClick() I can see that causing a scoping issue. Try moving handleButtonClick() into the same block as the table initialisation.

    Actually I think this is more involved. You are attempting to use a React event handler from a rendering function, as if there return was JSX. That is not possible in DataTables - sorry.

    You would need a global event handler (or at least at the component level) that would listen for the click event and then act on it.

    Better integration with React is something I plan to look at in future.
