In launch instance page, the select network page's layout is not as others

[tinytmy]

In launch instance page, other page layout: left is col-sm-6,right is col-sm-6.
but in select network page the layout is not as that, and I look the page has
css <td class="actions">, <td class="help_text">, there is no code about .actions .help_text in
https://github.com/openstack/horizon/blob/master/openstack_dashboard/static/dashboard/scss/components/_workflow.scss.
In juno it has those css(https://github.com/openstack/horizon/blob/stable/juno/openstack_dashboard/static/dashboard/scss/horizon_workflow.scss#L9).
