Hi,
I've created a GUI in Matlab with 4 pushbuttons and a table. I want to set initial values in the table when the GUI opens, and then change the values in the table when one of the buttons is pressed.
I'm new to this, what do I need to do to set the data in my uiTable1? I feel like this should be easier then I'm making it. I don't want the user to be able to change the cells of the table, I just want to change the cells of the results from a code that I will run as a display.
Thanks,

I got the set command to work. Now I'm having trouble figuring out how to change the data in the table only 2 cells at a time. For example the table is 2x10. When the user clicks a button, I only want data in cells (1,1) and (2,1). Then when they push the button a second time, I want to read the table values that are already there but then add in cells (2,1) and (2,2). Do you have any suggestions for this? I'm having trouble figuring out which cells already have data using the getappdata command.

Get the old values using the get command, concatenate them together and then set them again:
newVals = randn(1,2);
oldVals = get(t,'Data');
newVals = [oldVals ; newVals];
set(t,'Data',newVals);

This works, great, however I want the first column to be replaced, but then every column after that to concatenate. How can I do this?
Is there a way to set a limit on the concatentation? For example once there are 10 columns I want the function to not allow any more concatenations?
And once the table is full, is there a way to sum all of the values in each column and return a result in a popup window?

I figured out my first problem with how to replace the first value. Now I need to figure out how to limit the number of concatentations and then return a popup window at the end

Sure just place this in an if statement (checking the size of the 'Data'), make a new figure, and add a uitable or annotation('textbox',...) with the data.

Use the set command:
f = figure;
d = randn(10,3); % Make some random data to add
t = uitable(f);
set(t,'Data',d); % Use the set command to change the uitable properties.
set(t,'ColumnName',{'a';'b';'c'})

t = handles.uitable1;
d = randn(10,3); % Make some random data to add
set(t,'Data',d); % Use the set command to change the uitable properties.
set(t,'ColumnName',{'a';'b';'c'})
