I have a case of AF Table symbol.
I tried using AF Table according to the attached link. I followed the instructions but there is a step I don't know how to do.
I use symbol to display only the value of the column as shown.
And the values of my row are not displayed.

I have downloaded the library but I don't know if symbol has queried the library yet ???

Or my code in the 2 images below has a problem.

I look forward to your help.
Thank you very much
