style alternating rows json code in Matrix

Hi Anonymous 

You can find a template of all theming options for the matrix visualisation here: github.com/deldersveld/PowerBI-ThemeTemplates/blob/master/Matrix.json 

It's great as a reference tool.

You'll need to make sure that "bandedRowHeaders" is set to true under the 'rowHeaders' and 'values' sections.

Hope it helps.

Best regards,

Martyn
