Error encountered when attempting to utilize ngTemplate to embed filter within a table

I am facing an issue with a component that includes a primeng table. Within a table row, I have an ng-container to project a p-columnFilter into the table from an external source. However, when trying to pass the filter into the template, I encounter a NullInjector error. This is due to the component from the external module not providing the necessary dependencies, even though it imports the required primeng modules.

ERROR NullInjectorError: R3InjectorError(RootModule)[Table -> Table -> Table -> Table]: NullInjectorError: No provider for Table! at NullInjector.get (core.mjs:11172:27) at R3Injector.get (core.mjs:11339:33) at R3Injector.get (core.mjs:11339:33) at R3Injector.get (core.mjs:11339:33) at NgModuleRef.get (core.mjs:21902:33) at R3Injector.get (core.mjs:11339:33) at NgModuleRef.get (core.mjs:21902:33) at Object.get (core.mjs:21579:35) at lookupTokenUsingModuleInjector (core.mjs:3374:39) at getOrCreateInjectable (core.mjs:3486:12)

Answer №1

After some experimentation, I discovered a solution by adding Table and TableService to the providers section of the module where the root.component is located. https://example.com/image.png

I realized that p-columnfilter doesn't function properly when used outside of a table without defining the necessary providers. Since ng-template only supplies content without actually creating it within the table, providers must be included.
