Table widget heading change

Hello, i want to overwrite the table widget heading with a translatable string but I didn't find how i could. I tried to use like this:

protected static ?string $heading = __('Parts Surveyed Products');

protected static ?string $heading = __('Parts Surveyed Products');

but it not accepting if i start with double underscore. If i use the static string it is working. Anyone faced with this before?
