Describe the bug
When applying a dark theme to the Docs page, the table still has white and light gray background colors. This obviously ruins the readability of the table as the text color is also a light gray. There is a hardcoded background-color: white; value applied to the table tr element.

To Reproduce
Steps to reproduce the behavior:

1. Use a dark theme for the docs page

We would like to avoid confusion like we have in webpack-contrib/webpack-bundle-analyzer#185

We could document statsFilename and reportFilename options allowing the use of an absolute file path like /path/to/folder so that people would know it's supported.

Let us know in this issue if you would like to contribute to this!
