WP-Table Reloaded enables you to create and manage tables in your WP’s admin area. No HTML knowledge is needed. A comfortable backend allows to easily edit table data. Tables can contain any type of data and additional JavaScript libraries can be used to extend it with features like sorting, pagination, filtering, and more. You can include the tables into your posts, on your pages or in text widgets by using a shortcode or a template tag function. Tables can be imported and exported from/to CSV, XML and HTML.
