add onHeaderClick on column properties

[ds3783]

In out product document, product manager require a feature that is: when user click table header, system popup a modal dialog which explain that specific column is how generated.
Thus, I think we need a event listener function pass to the "th" element.

Try using column[title]:

const columns = [
  { title: <span onClick={handleTittleClick}>Name</span> }
];

@ds3783 ， it can use now?

Does this onHeadClick not need to provide parameters?

Because in my needs inside, I was hoping to click thead to be able to sort。I need to know some information, such as the current thead。

I see your code，but it cannot help me
