Data table filter

dzcatic

I am using Individual column searching (select inputs). I was wondering is it possible to set filter for specific columns, not all of them?
Script I am using:

$(document).ready(function() {
$('#table').DataTable( {
initComplete: function () {
var api = this.api();

        api.columns().indexes().flatten().each( function ( i ) {
            var column = api.column( i );
            var select = $('<select><option value=""></option></select>')
                .appendTo( $(column.header()).empty() )
                .on( 'change', function () {
                    var val = $.fn.dataTable.util.escapeRegex(
                        $(this).val()
                    );

                    column
                        .search( val ? '^'+val+'$' : '', true, false )
                        .draw();
                } );

            column.data().unique().sort().each( function ( d, j ) {
                select.append( '<option value="'+d+'">'+d+'</option>' )
            } );
        } );
    }
} );

} );
