function UITableSelectionChanged(app, event)

            T=CaricaListaStrategie_Aggreg_Struct(app.predator_Equity," ",selection); 
  end
 
  
 selection =
 
     1     5 

 if i touch circle green 
   selection =
     1     5
     2     5
     3     5
     4     5
     5     5
     6     5
     7     5
     8     5
     9     5
     
How do I select only the column when you press on the green circle? (column name) (I would like to receive only "5" instead of having the whole array..
I know you could only consider the column in the array but I don't know if that's the correct procedure  
I need this to sort the columns in descending order depending on which ColumnName I press

Hi Luca,

I understand that you want to get the column name of a table when a cell is clicked. In MATLAB App Designer, it can be done by using the ‘CellSelectionCallback’ property of the ‘uitable’ component. This callback function is triggered when the user selects a cell in the table, and it provides information about the selected cell, including the row and column indices.

Here is an example of how to set up the ‘CellSelectionCallback’ and retrieve the column name:

        % Cell selection callback: UITable
        function UITableCellSelection(app, event)
           indices = event.Indices;
           if ~isempty(indices)
                % Get the row and column index
                row = indices(1, 1);
                col = indices(1, 2);
                
                % Get the column name using the column index
                columnName = app.UITable.ColumnName{col};
                disp(indices)
                % Display the column index and name
                disp(['selected cell in column: ', col, ":" , columnName]);
            end
        end
