Customise a Report Theme for Table and Matrix

HI,

I used the Power BI Desktop GUI to define custom colours and font etc, My background is purple and colours used are defined below. The THeme 'works' for most of the Visuals I use however it doesn't for Tables and Matrix's - these are still appearing in white with black font. I have tried to edit the JSON file to define TableEx attributes but all my other visuals defualt to the factory/standard settings; is there a way to define an entry to the JSON file for Table and Matrix that doesn't override the other settgins.

JSON code is below:

thanks in advance:
