CdkDrag with ng-content no drag directives and mat-table is pain

[boendermaker]

I'm working on a reusable mat-table component with ng-content projection and with dragsortable rows and columns, column resize.

It seems that cdkDrag directives doesn't work with ng-content projection, so i tried to use only the dragdrop service from cdk which seems to work but with usage of detectChanges() and i have to re-add all draggables to their droplists on each dropevent for the columns.

When adding additional rows / data to the table on runtime, the newly added rows doesn't get recognized and can't be dragsorted.

Am i missing something? Seems there isn't that much example or even documentation for such a case (See my github kitchensink for code)
