Limit displayed information from categories in dataview table


I want to create a table with dataview that displays all tags present in files tagged with #game. Easy so far.

Now, I want to hide the #game itself from the list because all the showed files have this tag. I just want to get shown the other tags from the files.

I haven’t found any way to limit this. With WHERE, I limit the chosen files, but I don’t limit the displayed categories from the chosen files…?

Thanks for helping.
