How to resize uitable?

I have a uitable extracting data from a database in my GUI which is displayed upon a click of a button.

I am sending 3 columns of data, however only one column appears with a horizontal scroll bar. I want the table to re-adjust the size depending on he number of columns sent as this can be seleced from 1-3.

Here is my code so far:

FinalOut = [Output, Output2, Output3]; disp(FinalOut);

ColNames = {TableType; TableType2; TableType3}; disp(ColNames);

uitable(handles.figure1,'Data',FinalOut,'ColumnName',ColNames,'Position',[250 20 150 300]);

Is there a way to make this table more flexible/dynamic depending on the columns of data sent, so the width of the table only is changed as data is loaded in?
