Can an action be added to an already extended button?

I think the answer is no, but thought I'd ask to double-check ...

buttons: [
                      
{ extend: 'columnToggle',
  columns: '.position',

  action: function ( e, dt, node, config ) {

    // do something in addition to toggling '.position' columns

   }
                            
},

],

Yes, but it will override the original action. You'd need to call the action of the original button as shown in the last example on the buttons.buttons.action page.

Sweet. Thank you Alan.

In mean time, I was resigned to doing something like this ...

buttons: [

 { text: 'Toggle Position Column Plus Do Something Else',
  
   action: function ( e, dt, node, config ) { 
   
    this.active( ! this.active () ); 
    
    dt.column( '.position' ).visible( ! dt.column( '.position' ).visible() );
    
    // do something in addition to toggling '.position' column
   
   }
  
 },

],
