Hi,
1. Please make sure you select Classic Editor on Settings > Writing. You can view installation guide on the plugin page here: https://wordpress.org/plugins/classic-editor/
2&3. Please install this plugin: https://wordpress.org/plugins/tinymce-advanced/. This plugin work with Classis Editor and Gutenberg. You can easily add a table or anything you want.
4. Please modify CSS code like this:
.post div#ez-toc-container ul li {
font-size: 15px;
font-family: Arial;
}
OR you should view your TOC plugin document and discover how to change the typography.
Best Regards,
