Table summation

Table summation

[Russell Adams]

Speaking of tables today, I thought I'd post a question that I haven't
found a simple answer for.

How do you sum a table reliably? (ie: tolerant of editing)

This table requires the use of org-table-insert-row (etc...) in order
to keep the formula correct.

| Header |
|--------|
|      1 |
|      2 |
|      3 |
|      4 |
|      5 |
|--------|
|     15 |
#+TBLFM: @7$1=vsum(@I..@II)

How can I do something like this, where the last cell is automatically
the sum of the column, and not an absolute reference that must be maintained?

|      1 |
|      2 |
|      3 |
|      4 |
|      5 |
|--------|
|     15 |
#+TBLFM: LAST=vsum($0..$0)

Thanks.

In reply to myself, perhaps a way to refer to last cell would work.

|     15 |
|--------|
|      1 |
|      2 |
|      3 |
|      4 |
|      5 |
#+TBLFM: @1$1=vsum($I..$LAST)

That way using tab on the value "5" would add a new line and not break
the formula reference.

Thanks.

I'm not sure how tolerant you mean.  Would it help to use @-I and @-II

By tolerant I mean not sensitive to absolute table references that
break if you use tab to add more rows at the bottom or C-k to kill
lines in between.

Thanks.

Hi Russel,

no, I don't see a good way to fix this.  Just get used to use
the proper commands to insert new lines.  To make it easier to
add new lines at the end, try

(setq org-table-tab-jumps-over-hlines nil)

The TAB will create new lines before horizontal separator lines.
Judging from your own follow-up message, this might be all you need?
