Frontend: mdc-data-table background color

[Strixx76]

Home Assistant release with the issue:
0.99.2

Last working Home Assistant release (if known):

UI (States or Lovelace UI?):
Lovelace

Browser and Operating System:
All

Description of problem:
Background color for the mdc-data-table seems to be set to white (#ffffff), and not inherited. But text-colors are.
This makes the table unreadable when you use a theme with dark background and white text.

Javascript errors shown in the web inspector (if applicable):

N/A

Additional information:

[SeanPM5]

The unused entities page uses a variable ha-card-background which most older community themes do not have defined, and so it falls back to the color from the default theme (white) in that case.

Add this line to your theme(s) and restart, and you should be good:

card-background-color: "var(--paper-card-background-color)"

Thanks!

That did the trick.
