how to unselect an item in data table?

Hi,

I am working on a “rect” plot and its entries are linked with a data table. When I click an entry in the table, the plot will highlight the corresponding area. This works fine. But I don’t know how to unselect the entry in the table. In another words, how to return to the state when nothing been highlighted.
