{#
    Sortable table headers ('<th></th>' blocks)

    If you're using this macro then you must comply with convention and use following query parameters:
        - query - search query
        - page - current page for pager
        - order-by - which column is currently used for orderring
        - order - order direction ('asc' or 'desc')

    'columns' argument must be an associative array like:
        'Human readable column name' => 'propertyName'
