[Table] Identify layout table

[renow-luxembourg]

Feature Request

In French-speaking countries, for accessibility audit we use the RGAA accessibility guidelines.

Is your feature request related to a problem? Please describe.
In the criteria 5.3, we test if each layout table (<table> only used to display information in cells) has an attribute role="presentation" to success.
This test failed :

• if the table doesn't have the role="presentation"
• if the table has a caption (<caption> tags)
• if the table has headings (<th> tags)

In some of our website, redactors use table to diplay content in column. For those websites, in the Accessibility Audit, we get a fail due to the missing role attribute.

Describe the solution you'd like
The simplest solution will be to automatically add the role="presentation" attribute to the <table> element when the user choose the "None" option in the Header selector.
On top of that a layout table shouldn't contain any <caption> tag, so it will be nice to disable this field when "None" is selected in the Header selector.

Are there alternatives?
We can also add a checkbox in the table tool to switch between data-table and layout-table.
