Named fields in tables

Named fields in tables

[Uwe Jochum]

I've seen this in Orgmode (4.68): If you use named fields in an Orgmode
table, the field name should not contain a "-", like in "sum-up". Field
names with this sign don't work (you won't get an error message, but the
formula with that field name isn't computed). I hope others can verify
this phenomenon.

Schöne Grüße,

Uwe

This is correct, because "-" is an operator.  How would you tell the
difference between "$sum - 2" and "$sum-2"?

Is that not documented?  Damn I guess I assumed this to be
obvious.  Not so.

Thanks

Carsten,

you're right: the "-"-problem should be obvious... But I am not trained
as a mathematician or a computer scientist, I am a humble literary
scholar and librarian who looks on the "-" as a simple dash, not an
operator. But I like to learn the way others think and computer programs
work.

Thanks for the explanation!

Uwe

Good to see "humble literary scholar" here!  Now we are at least two :)
