showSelected
Toggle a filter that will reduce the rows displayed to just those which are selected.
Please note - this property requires the Select extension for DataTables.
Description
It can be useful to give your end users the ability to filter a table just to the rows that are currently selected, particularly when working with larger data sets. This button provides that ability by toggling a filter when activated. Toggling it a second time will remove the filter and show all rows again.
Note that when in the filtered state, changing the selection does not automatically update the filter - the table will remain showing the rows that were selected when the button was activated until the next table redraw.
Please note that this button does not work with server-side processing enabled. It uses client-side processing specific mechanisms to operate.
Example
Show a button which will toggle a filter to show selected rows only:
new DataTable('#myTable', {
buttons: ['showSelected']
});
