How do I display a table which has another table as a variable in app designer app in Matlab?

The code below generates a matlab table which has another table as one of its variables.

test = [1;2;3];
test2 = [5;6;7];
test3 = [9;10;11];
tmp = table(test, test2, test3);
merged = mergevars(tmp,{'test','test2'},'NewVariableName','Combined','MergeAsTable',true);

I want to display a similar table in an app I am building in app designer. I do not find any info how to do that. I would be very grateful for any suggestions.

app.UITable.Data = merged 

does generate an empty table in the GUI. Thanks!

Hi Aynur,

You could try placing the following code in the startupFcn of the MATLAB App:

function startupFcn(app)
    test = [1;2;3];
    test2 = [5;6;7];
    test3 = [9;10;11];
    tmp = table(test, test2, test3);
    merged = mergevars(tmp,{'test','test2'},'NewVariableName','Combined','MergeAsTable',true);
    app.UITable.Data = merged;
end

The output of this would be as follows:

If the 'mergevars' function arguments are changed as follows, the output would vary as shown below:

merged = mergevars(tmp,{'test','test2'},'NewVariableName','Combined','MergeAsTable',false);

For more information you could look at the following documentation page which clearly illustrates the required functionality:

Table Array Data Types in App Designer Apps.

Hope this helps!

Hi Pavan, thanks for the response. However, your solution does not include variable names of the sub table. What I want is one header for 2 columns and each of these 2 columns should also have their column names.
