How to fill out a table in app designer

Hi everybody, I'm working with Matlab app designer for the first time. My question is: How can i fill out the rows of my table? I want that my results are stored in the table after I click on the button "Importieren und Berechnen". I've no clue how to deal with this issue, because most of the tutorial are generating a complete new table. My way to try to solve the was (random numbers):

column1=['PV','HH','WP','Eng'] % name of the objects in the first column
column2=[3;6;2;9] 
column3=[1;4;5;7] 
column4=[3;6;1;6] 
app.UITable=[column1, column2, column3, column4]

I really don't know how to properly solve the problem. My code generates an error.

Thanks for your help

What results? Where do these results come from?

They're calculated after clicking on "Importieren und Berechnen". Or what do you mean?
