The documentation build started to fail after #7276 was merged. Let's revert the PR and fix the bug.

👋 Hi! Thank you for contributing to the vLLM project.
Just a reminder: PRs would not trigger full CI run by default. Instead, it would only run fastcheck CI which consists a small and essential subset of CI tests to quickly catch errors. You can run other CI tests on top of default ones by unblocking the steps in your fast-check build on Buildkite UI.

Once the PR is approved and ready to go, please make sure to run full CI as it is required to merge (or just use auto-merge).

To run full CI, you can do one of these:

• Comment /ready on the PR
• Add ready label to the PR
• Enable auto-merge.

🚀

This indeed resolved the doc failures.

@mgoin The bug is quite subtle. Your PR succeeded in building html files, but failed to generate PDFs. That's why it (and subsequent PRs) passed the CI tests on doc build. I guess the table format has an issue, but am not sure what the exact reason of failure is.

I see, my apologies for the trouble @WoosukKwon. I will investigate building the pdf locally to see if I can find a better table representation.
