It's still not lined up.  I'm not a fan of the "line up all the ="
style, as it's a pain to maintain (and can be harder to read if the "="
is too far to the right), but mixing the two is worse.

[Yuantian]:
I need more clear about this.
The only difference here is that my function puts ONE tab before "=" and ONE white space after "="; 
but the other functions in this structure use TWO tabs before "=".  Is that what you want?

Regards,
Yuantian
