Tables with background-color

[mvlcek]

@mvlcek,
the correct notation is not "attribute" but "styles"

Thanks. Interestingly it works with "attributes", too.

Now I will try to find out how to do this in a custom file, but as you see it is possible to do (and I know now how to get rid of some of the rubbish from the default combo-box)

For the custom file, see my previous post.
(I found it by googling, as the documentation is definitely lacking in this aspect).
