Datatable headers have wrong sizes and datatable doesn't have the correct borders when in a card

The header of a data table should, according to the specs, have a 56dp height. Currently the implementation uses the same height as a normal row, 48dp. [0]

Also, the specs talk about embedding it within a card. When doing this the card header should be 64dp. Perhaps I'm using it wrong, but over here it renders with 61dp. [1]

The borders are also not correct. When in a card, the specs show the borders should wrap the card. The header then doesn't have a top-border, the last row does have a border and the footer also. Attached screenshots clearly shows the difference.
