Create interactive tables where learners fill in cells with text or numeric answers and get immediate, actionable feedback on each response. Instructors define the table structure using a simple Python-like syntax that specifies column headers, cell types, and correct answers, making it easy to build targeted exercises across any subject or course level. Learners engage actively with material rather than passively reading it, and the instant feedback loop helps them catch and correct mistakes in the moment. The Active Table XBlock fits a wide range of course topics, from data-heavy STEM fields to language and writing courses that rely on structured response formats.
