There are a lot of tables that use templates like https://en.wikipedia.org/wiki/Template:Yes (and many others, some of which are linked on that template's doc page).

This is not exactly the same problem as T85462, in which the table structure itself is created by the template. In the case of {{yes}}, which is used like this: {{yes|cell text goes here}}, and has the effect of turning the cell's background green while showing the text, it would be adequate to have this recognized as a plain template, and edit it like any other template.
