Hi, welcome to the forum.
It's a bit difficult to answer your question as I do not know what gp_clinical is. Is it some kind of public data base? If so in what country or international organization? If so can you supply a link?
What is the name of the application you are using? Do you mean R in general or are you referring to a specific R package?
table_exporter looks like it might be an R function. What package is it in?
Can you post any code you already have?
Copy the code and paste it here between
```
````
This gives us formatted code that we can copy, paste and run .
Please do not send screenshots. Often a person here does not have the time to type out code to test it.

Thanks.
Edit
What Operating System, Version of R and Version of RStudio?
