Cause: In the Closed view, the table header doesn't have the assignee column, but in the table body, there is an empty cell at the end of each row, causing the break in layout.

Possible fixes:
- Add the Assignee column to the table header and display the assignee in every row.
- Or, remove the empty cell at the end of each row in the table body.
