  return unless params[:sort] == column.name

  tag.span(params[:dir] == "desc" ? "↓" : "↑", class: "telm-sort-indicator")
end

#telm_sort_link(resource, column) ⇒ Object

Click cycles a column asc -> desc; clicking a new column starts asc. Changing sort resets to page 1 by dropping the page param; an active FK filter is preserved.
