Add strikethrough to deleted tables (#1325)

Make it easier to see which issues are deleted

Allow for further differentiation between issues
that the user wants and doesn't want by 
striking-through all text in the table.

This helps to give a visual difference between the
un-deleted issues, which should prevent confusion 
when the table headers are not visible.

Styles are applied via CSS override when referencing 
the component in CSS, using ::ng-deep.
