For the actions buttons such as :new, :edit etc, as well as custom buttons.

Custom buttons can be added to the list in :action_buttons

Example

  action_buttons: [:new, :edit, :super_cool_custom_action]

You can then define the function called for that action in the module where the table is defined. Don't forget to add your csrf_token.

  def super_cool_custom_action(socket, item, csrf_token) do
    link "SUPER AWESOME", to: Routes.super_cool_path(socket, :custom_action, item), "data-confirm": "Are you sure?", csrf_token: csrf_token
  end
