Hey @Kara Pastour,
If the basic Jira table is not enough, you could also just use the Table Grid app for Jira.
It offers rich table functionality. Plus, it allows you to view and edit tabular data, stored on local or external databases.
It also looks pretty sleek:
Anyway, we are the developers of the app. So do let me know should you have any questions at all!
Thank you so much Stefaan - appreciate your reply! We were needing to add a fairly complex data table to one of our JIRA tickets and I was confused as to why adding a table in JIRA was so different from adding a table (WYSIWYG format) in Confluence. I'll check out the table grid editor add-on. :)
