Infovarious Table No Auto Ads Plugin

Google AdSense “ad intents” can turn words inside your content into links, or show chips, that open a dialog with related ads. When this happens inside a table, the result can overlap or break the layout of the table.

Google documents a class named google-anno-skip that excludes a section of a page from ad intents. This plugin adds that class for you: it automatically wraps every table in your post content with a div element, so you do not have to edit each post by hand.

What it does

Wraps each table in post content with <div class="no-auto-ads google-anno-skip">.
Handles nested tables (only the outermost table is wrapped).
Leaves a table alone if it is already wrapped by an element that has the google-anno-skip class.
Does not run in the admin area, in feeds, or in embeds.
Has no settings screen, loads no scripts or styles, makes no external requests and stores no data.

What it does not do

It does not guarantee that no ads will ever appear near a table. It only adds the exclusion class documented by Google for ad intents. Other ad formats (for example in-page auto ads) are controlled in your AdSense account.
It does not change your AdSense account or settings.
It only affects content output through the the_content filter. Tables printed by a theme template outside the post content are not changed.

Customization

You can change the class names with the tnaa_wrapper_class filter. Keep google-anno-skip in the list, otherwise AdSense will not exclude the area.

add_filter( 'tnaa_wrapper_class', function ( $classes ) { return $classes . ' my-extra-class'; } );
