Table equations: II on lhs

Table equations: II on lhs

I am using a simple table to add up some estimates for tasks.  On the left
hand side of the equations in the TBLFM line I can't get an expression like
@II$2 to work.

Here's an example
| task  | estimate | probable |
|-------+----------+----------|
| one   |       12 |        2 |
| two   |       10 |        3 |
|-------+----------+----------|
| total |       22 |        5 |
#+TBLFM: @4$2=vsum(@I..@II-1)::@4$3=vsum(@I..@II-1)

I'd like to be able to put @II$2 on the LHS of the equation.  That way, when
I add a row to the table, the equation doesn't have to change.

A workaround for the above table is to use $LR2 and $LR3 instead of the more
general references.

I do this fairly often. Just use enter to add a row in the table, the
references are automatically updated. Now, if you copy and paste it
won't work.

I just tried your example with the LR, and that worked fine for me.

|-------+----------+----------|
| task  | estimate | probable |
|-------+----------+----------|
| one   |       12 |        2 |
| two   |       10 |        3 |
| three |        8 |        8 |
| three |        8 |        8 |
| three |        8 |        8 |
| three |        8 |        8 |
|-------+----------+----------|
| total |       54 |       37 |
|-------+----------+----------|
#+TBLFM: $LR2=vsum(@-I..@-II)::$LR3=vsum(@-I..@-II)

This isn't copy/paste sensitive at all.

Does that answer your question?

Hm.  I hadn't noticed that; thanks!
