I am trying to use custom themes to alter the appearance of straight tables.
From help.qlik.com (Widgets & Extensions \ Custom themes):
CSS styling is more general and flexible.
However, none of the following articles describe how to use css. From the "extended object styling" article, I gather that one may change (only) the header font color and size, and the content font color and size, using JSON.
Are there other things I can change through css? What I currently need in particular is the thickness/color of the header base line. However, in a "teach a man to fish..." fashion, I'd like to know if there is a place (in the code?) I can check to discover possible customization options.
