Bugfix
At tables tl:RowClassProvider can be configured. These compute a CSS class for each row. This allows to style rows based on technical criteria.
Probably since the tables are rendered using templates(#27350), this no longer works. tl:RowClassProviders are completely ignored.
Test
Start demo application and navigate to Administration > Monitor > DB schema view. The styles of the tables are different depending on whether the underlying table is abstract or concrete.
