How do I alternate row colors in active admin without it displaying "odd" "even" in the view?

For some reason when I use the 'odd', 'even' trick. It will also display the text on the view page above my table. So it'll show "odd" "even" based on how many rows there are in the table. It clutters up my page.

  panel 'Cities' do
        table do
          tbody do
            f.collection_check_boxes(:city_ids, City.select('id, name, state').order(:name), :id, :name_and_state) do |city|
              tr(class: cycle('odd', 'even')) do
                td(class: 'col col-checkbox') { city.check_box } +
                td(class: 'col col-text') do
                  city.label do
                    city.text
                  end
