The only way I found to do it was a bit hacky. ActiveAdmin will pass in the column name and asc/desc via the params hash, then you can add that to your query.

Also, make sure to pass "sortable: true" into the table_for call.

panel "P&L" do
  table_for Quote.order(params[:order].gsub('_', ' ')), sortable: true do
    column("Revenue", sortable: :revenue) { |quote| number_to_currency quote.revenue }
    column("Profit", sortable: :profit)  { |quote| number_to_currency quote.profit  }
  end
end
