+ * Powerful list view table component.
+ *
+ * Creates a sort-filter-bar and table with virtual scrolling, where projector and multi select is already
+ * embedded
+ *
+ * Takes a repository-service, a sort-service and a filter-service as an input to display data
+ * Requires multi-select information
+ * Double binds selected rows
+ *
+ * required both columns definition and a transclusion slot using the ".columns" slot as selector
+ *
+ * Can inform about changes in the DataSource
+ *
+ * !! Due to bugs in Firefox, ALL inputs to os-list-view-table need to be simple objects.
+ *    NO getter, NO return of a function
+ *    If otherwise more logic is required, use `changeDetectionStrategy.OnPush`
+ *    in your component
+ *
+ * @example
+ * ```html
+ * <os-list-view-table
+ *     [repo]="motionRepo"
+ *     [filterService]="filterService"
+ *     [sortService]="sortService"
+ *     [columns]="motionColumnDefinition"
