Unfortunately, there isn't a way to put an interactive checklist into a card. Potentially, you could create a webform and display the webform in a table card. The webform could be edited by the user once a task is completed. Using the Projects and Tasks within Domo would be much easier and cleaner.

In a table graph, alerts can only be put on a summary number. Alerts can be put on different chart types (ie. bar charts).
