#### Problem description

I've been running into an issue lately where when is use `to_clipboard` the results paste into excel with a lot of garbled text. Any idea what can be going on here? I haven't found any minimal example to consistently reproduce, but it is happening a lot for me. `to_exce`l still works interestingly enough, but I do prefer the convenience of the clipboard.

#### Expected Output

Not this:

Here's another to verify that it is rather random what I get:

#### Output of ``pd.show_versions()``

<details>

Does work for me. I get the following error:
```
ImportError: Can't determine version for tables
```

I'm on pandas 1.2.2 though
