What version are you using? I just patched a unique key prop bug today.

Check the render method of `src`. See https://fb.me/react-warning-keys for more information. This happens even including a very simple SubComponent: SubComponent={(x) => (<div>hi</div>)} I believe it is because the Expander Cell fields do not have a "key" attribute even though they are within the allVisibleColumns map. Expander Cell Code <https://github.com/tannerlinsley/react-table/blob/aa48ef57ee26b88dfa03d85f0364c06556b53356/src/index.js#L671> The pivot columns might have the same issue but I haven't tested it. Overall I'm really happy with this library. — You are receiving this because you are subscribed to this thread.

Hey Tanner I just updated to 5.0.2 and I'm getting this for my subcomponents.

line 780 doesn't seem to have key={i2} do you think that's the problem?
{SubComponent && ( <ThComponent className={classnames(

I don't think 5.0.2 has the commits that fix those warnings.

I think your commit (1e4f838) is the one that fixed it for SubComponents but that was merged after the commit marked 5.0.2. The commit after yours (e11fdab) fixes the warning for Pivot Tables.

I don't think like 780 needs a key field because it is not the top level component of an array or iterator.
