Currently, it's not possible to display the

Test results sample

in Slack notifications as a formatted table rather than as a JSON object or list of dictionaries. This is a known limitation that has been raised by several users. According to the knowledge sources, there's an open GitHub issue (#1079) specifically requesting this feature: "Formatting the test_results_sample as a table within the Slack alerts" [GitHub Issue #1079](https://github.com/elementary-data/elementary/issues/1079). Users have commented that this would be particularly helpful for non-technical stakeholders who are not familiar with JSON format. This request has come up multiple times in the Elementary community. For example, in a Slack conversation from August 2022, a user specifically asked about receiving the test results sample "as a table and not as a json" [Slack forum question](https://slack.com/archives/C02CTC89LAX/p1692089895796149). The Elementary team acknowledged this as a reasonable request but confirmed it wasn't currently possible. If this feature is important to you, you might want to follow or comment on the existing GitHub issue to show additional interest in this enhancement.
