Since: KeyTable 2.0.0

KeyTable has blurred focus from a cell.
Please note - this property requires the KeyTable extension for DataTables.


While it is often useful to know when a cell gains focus (key-focus) it is equally useful to know when that cell loses focus. This event provides that ability and is triggered whenever a cell's focus is blurred. This can be the result of:

  • Focus moving to a different cell
  • Focus leaving the table (keys.blurable).

This event will occur prior to the key-focus event (if there is a cell to be blurred - i.e. two cells can never have focus at the same time). Additionally, if a DataTables page change is required to display a newly focused cell, this event will occur before the page change is triggered.


function function( e, datatable, cell )



Show information about a cell when focus is changed:

var table = new DataTable('#myTable', {
	keys: true

	.on('key-focus', function (e, datatable, cell) {
		var rowData = datatable.row(cell.index().row).data();

		$('#details').html('Cell in ' + rowData[0] + ' focused');
	.on('key-blur', function (e, datatable, cell) {
		$('#details').html('No cell selected');
