TablePress is a WordPress plugin that simplifies the creation of complex tables in WordPress. This is one of the best designed, most thorough plugins I’ve seen for WordPress in a long time. It handles all the heavy lifting of formatting, organizing and displaying tables according to the user’s preference.
TablePress enables you to create and manage tables on your WordPress site. No HTML knowledge is needed, as a comfortable interface allows to easily edit table data. Tables can contain any type of data, even formulas that will be evaluated. An additional JavaScript library can be used to add features like sorting, pagination, filtering, and more for site visitors. You can include the tables into your posts, on your pages, or in text widgets with ease. Tables can be imported and exported from/to CSV files (e.g. from Excel), HTML files, and JSON.
