This is looking good!

Do we expect this PR to support running TabDDPMSynthesizer in the single-table benchmark, including running it on AWS and GCP?

If so, could we add integration tests for benchmark_single_table()?

For AWS and GCP, I previously tested this manually and shared the result folder in the PR. For example, for #549, this is the test folder

I can help for testing it on AWS and GCP

We're expecting that they will never update their library right? That is why we're moving all the code into here?

Yes exactly, the last update made to the repo was 3 years ago. It's unmaintained code that if we'd like to benchmark then we should copy over the code.
