* It is a good practice to **resolve dependencies** from the `PeriodicBackgroundWorkerContext` instead of constructor injection. Because `AsyncPeriodicBackgroundWorkerBase` uses a `IServiceScope` that is **disposed** when your work finishes.
* `AsyncPeriodicBackgroundWorkerBase`**catches and logs exceptions** thrown by the `DoWorkAsync` method.

- **visible** is a predicate that will be used to decide if the cell content of this entity prop should be displayed on the table or not based on the data record. (_default:_ `() => true`)
- **columnVisible** is a predicate that will be used to decide if the column of this entity prop should be displayed on the table or not. (_default:_ `() => true`)
- **tooltip** . is a tooltip for table column (_default:_ `undefined`)
> Important Note: Do not use record in visibility predicates. First of all, the table header checks it too and the record will be `undefined`. Second, if some cells are displayed and others are not, the table will be broken. Use the `valueResolver` and render an empty cell when you need to hide a specific cell.
