Answer 1

The simplest way I know of to do this is to use the Formatted Numbers plugin

Here is an example:

jQuery.extend( jQuery.fn.dataTableExt.oSort, {
    "formatted-num-pre": function ( a ) {
        a = (a === "-" || a === "") ? 0 : a.replace( /[^\d\-\.]/g, "" );
        return parseFloat( a );
    },
 
    "formatted-num-asc": function ( a, b ) {
        return a - b;
    },
 
    "formatted-num-desc": function ( a, b ) {
        return b - a;
    }
} );

$('#tbl_jaar').dataTable( {
     columnDefs: [
       { type: 'formatted-num', targets: 0 }
     ]
  } );
