+    Demo Program - Table with checkboxes
+
+    This clever solution was sugged by GitHub user robochopbg.
+    The beauty of the simplicity is that the checkbox is simply another column in the table. When the checkbox changes
+        state, then the data in the table is changed and the table is updated in the Table element.
+    A big thank you again to user robochopbg!
