Install Tabulizer for WordPress first. This is an add-on rather than a standalone plugin: it needs Tabulizer for WordPress 7.0.20 or later already installed and active, and until it finds it, it registers nothing and simply says so in your dashboard. Download Tabulizer for WordPress from the link above, install and activate it, then install this package the same way Plugins › Add New Plugin › Upload Plugin. It currently supports three page builders: Elementor, Divi (either the Divi theme or the standalone Divi Builder plugin) and WPBakery Page Builder. If you use none of them, you do not need this download.
