Update custom table entry.

Provide an array of columns and their values.
Important: Although this is a PUT method, it behaves like a PATCH request, meaning you only need to send the fields you want to update, and any other fields will remain unchanged.
Values can be any of the supported field types.

Note: You can use Examples > Request Example option for a basic example, however, we recommend that you copy the endpoint to Postman and test more complicated structures using the JSON editor.
