Header characteristic cell (table interface)?

Question

Hi folks,
I'm using a table interface (herited from cl_rsr_www_modifiy) to customize the data cell value.
I want to add a link which will contain as url parameters the corresponding row and header  characteristic_cell i_chavl of the data_cell.
To get the current row characteristic_cell i_chavl, I redefined the method characteristic_cell as follow :
IF I_X = 1.
  L_FILTER = I_CHAVL .
ENDIF.
Thus the method data_cell can retrieve the corresponding row i_chavl.
The problem is to get the header i_chavl... If I use the same way as above, I will only get the latest header i_chavl value of my table (since that a table is created from left to right, up to down)...
How can I get that header back for the method data_cell?
I was thinking of defining cell_content_id to the header characteristic cells and get it back by a javascript function call...
Before going futher, I would like to listen to your suggestion.
Thx
Bvs

You can define an additional table (on a structure) as attribute to your class.
In the characteristic_cell definition, you can populate this structure (alogwith i_y value)
In data_Cell you can read this table based on i_y value.
In start method, you can refresh this table.
I am sure there is an easier way (you can access all information in n_r_request) in data_cell method, but you will need to explore n_r_request to see where the relevant information is. In this case you won't need to do the above.
