welcome to the community!
here's an app that you may find useful: JXL for Jira.
JXL is a full-fledged spreadsheet/table view for your issues that allows viewing, inline-editing, sorting and filtering by all your issue fields, much like you view and manipulate data in e.g. Excel or Google Sheets. It also comes with advanced features such as issue hierarchies, issue grouping, and sum-ups, enabling you to perform various kinds of capacity planning.
As an example, here's a JXL sheet that shows the story points per sprint and assignee, updated live as we set the estimates:
Disclaimer: I work on JXL.
Any questions just let me know,
Best,
