  <p>When i see the table in XS screen view ,the spacing between the table columns is not properly adjusted..</p>
  
  <p>Is there a way out where i can add a horizontal scroll to space the table columns properly by specifying a min width to my table and adding a horizontal scroll when in XS and SM screen sizes.</p>
