With due respect, the instructions for App Designer are at best counter-intuitive and hermetic. For example, how to create a Table with 3 columns and 3 rows (besides the row of column headings), name columns AND rows, and populate the cells with Default values. Make these cell data entries editable by the user when running the app. The app sould take these Table data (and other data from the Slider, Knob, etc.), run a code that generates a plot.
I am stuck in trying to add Row Names. The User Community advises I need to add Table data first. But there seems to be no place in Design View to add such data!

If you share that snippet of code I might be able to help. Also, I'll move the response to the 'answers' section so others may find it useful in the future.

To add data to a UItable in App Designer, use the startupFcn() after creating the table in the UI.
  1. From the App Designer in design mode, right click anywhere on your app background, hover your mouse over 'callbacks', and add a startupFcn callback.
  2. Go to Code View and you'll see the startupFcn. Add your data to your table there. Refer to the documentation below to change other properties of the table.
app.UITable.Data = {1 2 3 4};

In the link, see the image in the first step. You must select your app in the component browser.

Should really have a way to initalize in properties with at least one empty row.....
Here's what I did in the app startupFcn
app.ColorsUITable.Data = cell(1,length(app.ColorsUITable.ColumnName));

That is the way to initialize a table with 1 empty row.
For some data types you can use <missing>

You can edit the RowName, ColumnName and ColumnEditable Properties of a UITable from the Property Inspector of App Designer.
You cannot add Data to a UITable from the Design View of App Designer, you will need to add the data in a StartupFcn (or other callback). For example
function startupFcn(app)
app.UITable.Data = rand(2,4);
end
Will result in:
