what you are looking for is presumably the ‘selectionChange’ event of the sap.m.Table, which is the basis for both the ‘Table’ as well as the ‘TableEnhanced’ widgets available in the Standard Content for Simplifier. After subscribing to that event, you could call the ‘getSelectedItems’ method on the table in order to determine the amount of selected items / checkboxes and act accordingly. If you need to deselect all items / checkboxes programmatically, there’s the ‘removeSelections’ method to do just that.
