Hi, I want to create a table of a certain size. Lets say rows are based on a number which I need to give input to the app. and the column is fixed. only one for now.
Is this possible. For now I created manually by writing 5 times the same code .. Please help me getting through this.
Please find the attachment of the mlapp file.
I am thinking to add a for loop for this section to automate it.
v = evalin("base",'original_proj_list'); % To import a variable from our workspace
v = ['Select';v(:,1)];
roll_nos = xlsread("./name_CGPA_2.xlsx");
roll_nos = ['Select';string(roll_nos(:,1))];
%for i = 1 : length(roll_nos)
app.StudentInfoDropDown.Items.i = roll_nos;
app.ProjectInfoDropDown.Items.i = v(:,1);
app.StudentInfoDropDown_2.Items = roll_nos;
app.ProjectInfoDropDown_2.Items = v(:,1);
app.StudentInfoDropDown_3.Items = roll_nos;
app.ProjectInfoDropDown_3.Items = v(:,1);
app.StudentInfoDropDown_4.Items = roll_nos;
app.ProjectInfoDropDown_4.Items = v(:,1);
app.StudentInfoDropDown_5.Items = roll_nos;
app.ProjectInfoDropDown_5.Items = v(:,1);
%end

Hi,
You can dynamically create a table when '#rows' are given as input in your app. This can be done by placing the code to create a table in the callback associated with the button that has to be clicked when '#rows' are entered.
For proper syntax to create a table:

This example might help you too!

I couldn't make sense of the code, where you are trying to populate every dropdown with same variables 'rollnos'. I can only help you, if you can elaborate on what you wanted to achieve.
Hope this helps!
