is possible to use a cell reference to a table
or spreadsheet as a property value?

Example:

***** lunch
      :PROPERTIES:
      :CASH: #lunchtable:@>$2
      :END:

      #+NAME: lunchtable
      | date             |    cash |
      |------------------+---------+
      | [2014-02-10 lun] |   16.00 |
      | [2014-02-07 vie] |   27.00 |
      |------------------+---------+
      |                  |   43.00 |
      #+TBLFM: @>$2=vsum(@I..@II);%0.2f

... and align numbers in the columns view?

*** 2014-01...
  | *** 2014-02          | 447.00  |
  | **** income          | 1000.00 | ...
  | **** expenses        | -553.00 |
  | ***** dinner         | -110.00 | ...
  | ***** party :-)      | -400.00 | ...
  | ***** lunch          | -43.00  |

thanks and sorry, English is not my language :-(
