[CdkTable] Provide a possibility to set the top offset for the sticky header

[ffriedl89]

Please describe the feature you would like to request.

I would like to have the possibility to set the top offset for the sticky header in the cdk table.

What is the use-case or motivation for this proposal?

As you can see in this stackblitz there are certain layouts that would need to have a different value set a sticky header-row / row. If you have any other element above that has position fixed or sticky you might want to change the top value that gets set by the stickyStyler.

Maybe a solution would be to provide a token for DI that can be used to set this value to something different than 0.

Is there anything else we should know?

Thank you for submitting your feature request! Looks like during the polling process it didn't collect a sufficient number of votes to move to the next stage.

We want to keep Angular rich and ergonomic and at the same time be mindful about its scope and learning journey. If you think your request could live outside Angular's scope, we'd encourage you to collaborate with the community on publishing it as an open source package.

This is still a problem today. You can add an offset using css with :

    .mat-table-sticky {
      top: 63px !important;
    }

But it would be great to have a way to set it dynamically so we don't have to rely on fixed value.
