Thread Subject: adding data to uitable

I am programming a GUI. I have a uitable that may potentially contain tens of thousands of records. I have no problem adding the data to the table, however it appears as if MATLAB does not make the data visible until you scroll to a portion of the table and takes a while (several seconds) to show the data after scrolling down. This is a problem because this makes it look like something is broken to the eyes of the ever impatient average software user. Is there a way to force MATLAB to make all the table data "visible" even before the user of the GUI scrolls down in the table?
