Reproduction steps:

1. Set up CKeditor by adding the necessary properties:

editor.wysiwyg.default=ckeditor
editor.wysiwyg.portal-impl.portlet.ddm.text_html.ftl=ckeditor
editor.wysiwyg.portal-web.docroot.html.portlet.announcements.edit_entry.jsp=ckeditor
editor.wysiwyg.portal-web.docroot.html.portlet.blogs.edit_entry.jsp=ckeditor
editor.wysiwyg.portal-web.docroot.html.portlet.mail.edit.jsp=ckeditor
editor.wysiwyg.portal-web.docroot.html.portlet.mail.edit_message.jsp=ckeditor
editor.wysiwyg.portal-web.docroot.html.portlet.message_boards.edit_message.html.jsp=ckeditor
editor.wysiwyg.portal-web.docroot.html.taglib.ui.discussion.jsp=ckeditor
editor.wysiwyg.portal-web.docroot.html.taglib.ui.email_notification_settings.jsp=ckeditor

2. Startup Liferay
3. Create a Basic Web Content
4. Add a table and fill out Summary field
5. Copy the source code to https://validator.w3.org/#validate_by_input

Expected:
No errors about the summary attribute

Actual behavior:
Error: The summary attribute on the table element is obsolete. Consider describing the structure of the table in a caption element or in a figure element containing the table; or, simplify the structure of the table so that no description is needed.
