Event for Table Row Deselection

Summary

Need to know if there's an event which is fired when a row is deselected in a table.

Hi,

I have two queries:

(1) Is there any event which is fired when a row in a table is deselected? I have a single-select table where selecting a row enables a button. However, deselecting a row, that is, when no row is selected in that table, should disable the button. Is there any event which can handle this? If no, is there any workaround for this?

(2) Is it possible to automatically deselect a row whenever the use clicks somewhere else on the page, like on an empty space with no UI element?
