Fix table header color for unsortable headers

+1

attached.

In order to address the issue I made a commit.

Proposed Solution: I've addressed the table header color issue by increasing the CSS specificity for the affected styles. In order to ensure compatibility with various use cases and avoid potential regressions, I've retained the existing !important declarations for now. However, with the increased specificity, some of these might be redundant. It would be worthwhile to have a follow-up issue to assess and potentially clean up any unnecessary !important declarations.

Changes Made:

- Updated the CSS selector from table { to table.table { to increase specificity.
- Retained existing !important declarations for safety.

Testing: The changes have been tested locally in various scenarios, and everything seems to function as expected. I'd appreciate feedback.

@tguerineau Thank you for the patch. I tested it in my environment and it fixes the issue! I will mark this RTBC. Your suggestion for cleaning up !important is a good process as well.

Just curious, are you using this theme for any of your projects?
