Scrolling table. Getting Number of Visible rows from User Settings.

Question

Hello everyone,
I hope you can show me the way to the light! here is my problem:
I have to control the scroll of a table, for allow to the user to see always one blank row for entry proposes.
For that I know that I can ge the number of visible rows and the first visible row through the methods:
cl_wd_table->get_visible_row_count( ).
cl_wd_table->get_first_visible_row( ).
The problem is that the user can modify the number of visible rows through the user settings in the table ( right button on the table "User Settings->more..." ) and it doesn't modify the value returned by the method cl_wd_table->get_visible_row_count( ).
How could I get the visible rows set up by the user in his user settings for control the scroll dynamically?
Many thanks in advice.
G.

Hi G,
The changes what user will be making will be classified as personalization.
I was looking into the ways of finding the user specific personalization in the code and then callin the mthod set_first_visible_row.
There are few classes related to personalization like CL_WDR_PERSONALIZATION_SERVICE and CL_WDR_PERS_MANAGER.
I tried calling method get_pers_data of class CL_WDR_PERSONALIZATION_SERVICE. But for me it was not returning any data.
You can also look into these classes and try to fetch user specific personalized data with methods available.
Another way which I thought is to create a component  configuration and make the number of rows as Final so that end user is not able to personalize this ( I know u won't agree on this  ).
@ Thomas: Any specific inputs from your side on this problem.
