Thank you for this PR. I have a few comments. IMO, showing all error values should be optional and controlled using a parameter. Imagine a scenario where a dataset with 1,000,000 rows fails on all of them.
The solution I recommend here is that by default, the behavior stays the same. I can see a few options here to consider - a parameter to set the number of displayed rows and a parameter to show all rows. The latter probably should add some pagination to the table. Also, you will need to adjust the header, as it clearly says that this is only a sample. If you show all errors, than the word "sample" should be removed.
Besides that, two small things:

1. Please bump the package version. We follow the X.X.X.900X convention for the development version, so simply change the last X.
2. The change is going to belong to the development version, so please follow my suggestion in the changelog.
