Awesome Table Understanding Datasets

A curated list of datasets that can be directly used or adapted for various table understanding tasks.

Note that some of the datasets provide only metadata and annotations, without the source files. Additionally, several datasets have download links that are no longer active. Since the authors may resolve this issue in the future, these datasets are still included in the list.

The repository will be continuously updated ✏️. If you find this resource useful for your research, just ⭐️ it and stay tuned!
