Is there another file/place that I'll need to update (other than the `usage.py` demonstrating the feature)?\r\n\r\nThanks!\r\nG","author":{"url":"https://github.com/gkiar","@type":"Person","name":"gkiar"},"datePublished":"2018-08-29T16:51:08.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/87/dash-table-experiments/issues/87"}
