[Orgmode] Re: evaluating rows or columns in org-table

Sorry that last post was unfinished.

Here's my attempt at fixing the student rank

|   | Rank | names      | grade 1 | grade 2 | grade 3 | Total | Letter grade |
|---+------+------------+---------+---------+---------+-------+--------------|
| # |    1 | student 01 |   91.80 |   96.40 |   97.00 | 95.07 | A            |
| # |    3 | student 03 |   92.00 |   95.14 |   97.00 | 94.71 | A            |
| # |    2 | student 02 |   88.78 |   89.15 |   98.00 | 91.98 | A            |
| # |    4 | student 04 |   84.00 |   74.62 |   88.00 | 82.21 | B            |
#+TBLFM: 
$7=($4+$5+$6)/3;%.2f::$8=if($7<60,F,if($7<70,D,if($7<80,C,if($7<90,B,A))))::@2$2=1::address@hidden

You can sort the table by the total column descending to get the rank.

If you sort the resulting table like this:

 1) Position cursor on any total value
 2) M-x org-table-sort-lines
 3) N (for reverse numeric sort)

Then update the Rank column with C-u C-u C-c C-c anywhere in the table
the rank numbers are recomputed starting from 1 on the first row.

I hope your blank lines aren't too important because sorting puts them
all at the bottom of the table.

Does that do what you want?
