[O] tables with column and row numbers

[Uwe Brauer]

Hi I found parts of the solution on that list but the following example
generates a table with column and row numbers.

  | 1 | 2         | 3         | 4 | 5 |
  |---+-----------+-----------+---+---|
  | 1 | x1        |           |   |   |
  | 2 | some data | more data |   |   |
  |---+-----------+-----------+---+---|
  | 3 | more      | data      |   |   |
  | 4 |           |           |   |   |
  | 5 |           |           |   |   |
#+TBLFM: @1=vlen(@I$1..0);EN::address@hidden

I am not sure whether this is the most elegant or robust solution but
maybe some words in the manual wouldn't harm.
