When I make the heading of a class wikitable, I can use a "!" or a "|" to start a line.
When I use "!", then the background color of the line is as I want it, but all text in it will be written in bold.
When I start a line instead with "|", then I don't know how to make the same background color as above, but the text won't get bold.
How can I make a special background color in any line of class wikitable, without getting the line text bold?
