I'm trying to export a file in html and add the class Even in the table lines, in even numbers, instead of the Odd class, because I really need this way so I can use in my site.
I tried using <tr$if($even(!%_counter%), class="even",)>, but it seems there is not this function.
As there is the function $odd
(see https://docs.mp3tag.de/scripting for the functions),
it should not be too difficult to invert the $if or apply a non-function for the odd-case:
<tr$if($odd(!%_counter%),, class="even",)>
