The only way to affect the row height, as Yair explains here (msg 5/6), is to reprogram the resizing callback.
On the other side, adjusting the fontsize automatically adjusts the row heigth.
f = figure('Position',[200 200 400 150]);
dat = rand(3);
t = uitable('Parent',f,'Data',dat,'Position',[20 20 360 100],'FontS',13);
