How do I do custom rendering?

[chl3188]

Hello
I use version v8

I want to customize the value that is rendered according to the table header.
For example, if the id of the table header is 'priority', we want to write 'general' if the value is 0, and 'administrator' if the value is 10.
However, if I import the value as flexRender(), I am worried that the value is not imported as the number type, which is the value.

Is there any option that can be custom rendered for each table header?
