Assuming that there are 4 columns in the UITable, you can append the data to the table by using the following example code.

% Button pushed function: Button
        function ButtonPushed(app, event)
             newData = {1 2 3 4}; %sample data for each column
             app.UITable.Data = [{app.UITable.Data{:}};newData];
          end

newData corresponds to the data that you want to add.

Previous answer does not work for a numeric table. Here is a working example to add/remove rows with push button event for numeric table:

          % Button pushed function: btnAddCycle
          function btnAddCycleButtonPushed(app, event)
              newData=[0 0 0];
              % Add 1 row to table
              app.CycleTable.Data = [app.CycleTable.Data;newData];
              % Update data component
              app.data.LoadCycle=app.CycleTable.Data;
          end
          % Button pushed function: btnRemoveCycle
          function btnRemoveCycleButtonPushed(app, event)
              % remove last row of table
              app.CycleTable.Data(end,:)=[];
              % Update data component
              app.data.LoadCycle=app.CycleTable.Data;
          end
