Set Dropdown values depends on other Dropdown value in Webdynpro Table

What is this about:

In this Document I would like to explain how we can set dropdown values depend on user entered value(dropdown).

What I have done:

I created simple webdynpro view with table of 2 fields country and languages.  I set Country filed as DropDownByKey and language field as DropDownByIndex. To know the difference between this two types go through  http://help.sap.com/saphelp_nw04s/helpdata/en/bb/69b441b0133531e10000000a155106/content.htm.

So languages available depends on country selected .

I created table node and bind it to table value.In table node I created another node which has attribute ‘LAN’ which holds the language as shown below.
