figure(1)
t = uitable;
set(t,'Data',rand(10,3));
data = get(t,'Data');
figure(2)
aH(1) = subplot(1,2,1);
aH(2) = subplot(1,2,2);
plot(aH(1),data(:,1),data(:,2));
plot(aH(2),data(:,1),data(:,3));

You need to convert the table data into numbers, and you need the time for the plot. Try this:
data = str2double(get(handles.table,'data');
plot(axes1, t1, data(:,column's name1));
plot(axes2, t2, data(:,column's name2));
