Asigning colors to a custom table with the colorPalette object.

[Anonymous]

Hi,

As Power BI can't handle dynamic headers through their native table views we created a custom visual that handles this issue. 

While we were adding custom styles based on a selected theme into our table to look similar to the out of the box visual; we found out that the color theme property affecting the border-bottom was the tableAccent. However, we could not map that property using the Visual.ColorPalette object.

Is there any way to extend the ISandboxExtendedColorPalette and add the tableAccent property? Is it possible to retrieve this attribute?

Thanks,
