Webform results table not displaying
the Results and Table aspects you refer to are purely Drupal components. We have built many hundreds of webform_civicrm forms and have never seen a problem with this so I doubt the problem is specifically an issue due to using civicrm.

You could try right-clicking and using your browsers 'inspector' to check the console and see if it shows any errors.

Otherwise try searching/asking in either the Drupal stackexchange or in the Drupal project Issues pages - and hopefully they won't say 'this is a civi issue' (unless of course it is and I am wrong)
