title: Kivymd MDDataTable failed to execute
body: <p>I was trying this simple code about MDDataTable, but it always gives me error every time I execute it. Recently I successfully ran different KivyMD function but this simple table is giving me headaches.</p>
  <p><strong>Python Code</strong></p>
  <pre><code>from kivymd.app import MDApp
  from kivymd.uix.screen import Screen
  from kivymd.uix.datatables import MDDataTable
  from kivy.metrics import dp
  
  class Demo(MDApp):
      def build(self):
          screen  = Screen()
          table = MDDataTable(orientation = &quot;lr-tb&quot;,
                              column_data = [
                                  (&quot;Food&quot;,dp(30)),
                                  (&quot;Calories&quot;, dp(30))
                              ])
          screen.add_widget(table)
          return screen
  Demo().run()
