[Table] Add input for sticky headers

[andrewseguin]

Add an input to <cdk-table> that makes the table's header stick to the top of the scroll container.

Interim solution: Use styles position: sticky; top: 0 on the header element.

Using sticky position, interim solution has some bugs when you navigate through pages in a table, if you're not at the top of the table when you change the page, header disappear, any solution ?

sticky position is not supported in IE. When will we see a cross-browser solution?

Hello @andrewseguin, any solution to the problem related to the interim solution?

[andrewseguin]

You can use position: sticky; top: 0 on the header row for now. Unfortunately this isn't a valid solution for IE but we have an implementation for this that we'd like to introduce soon.

It's not really working on Firefox too, and in Chrome navigating or changing items per page cause bug.
I know this feature is not urgent but have you an idea of the delivery date of this?
