    cell_value(row, "author.name") -> the cell text (also used by the detail page)
    table(columns, rows, caption=None, empty=None, classes="")

            {"attr": "author.name", "label": "Author", "link": True,

          `attr` is a dotted path, read with item-then-attribute lookup;
          a callable value is called (`get_status_display`). `link` wraps the
          cell in a link to the row's get_absolute_url() (or row.url).
        rows: model instances or mappings (`object_list`).
        Row actions: call it with a block, which receives the row:
            {% call(row) table(cols, object_list) %}
                <a href="{{ url('item-edit', pk=row.pk) }}">Edit</a>
            {% endcall %}
