static and dynamic data in row

Hi
I want a grid which contain static values in rows in first and third columns and second column should contain data loaded from MySQL database. I have a table structure in XML and data for second column are loaded from php file. I was using this:

grid.load(“my_xml_file.xml”);
grid.load(“my_php_file.php”);

and the problem is that grid showed xml and then rerender the whole grid with php file (there is script for DB data).
Is there any options how can i only rerender only second column? Or else, is there a possibility how I can set name for grid rows for first column and load data to next column and next column will hav rows with static text again?

Unfortunately such feature is not supported
