Hey @gormster,

😒 Your PR doesn't modify any tests, so it's hard to know what's being fixed, and your changes might regress in the future. Please consider adding tests to cover the change you're making. Including tests allows this PR to be merged by yourself and the owners of this module.

This can potentially save days of time for you!

🔔 @Jojoshua @mike-lischke — please review this PR in the next few days. Be sure to explicitly select Approve or Request Changes in the GitHub UI so I know what's going on.

There's no tests for mutators at all rn - I'm not even sure how I'd write them - so I thought that probably better left to someone who's more familiar with both the Tabulator codebase and unit testing in DT.

@gormster The tests here do not read or set any value. It's all about syntax. In the test file you write some code, which must be allowed by the type definitions. In your case just add a column definition at the end of the test file, which uses a mutator. You can probably use your own code here, for which you added the mutateLink field.
