Don't output table display view mode if all sub-fields are empty

With the exception of the table display, the field shouldn't get rendered when it's empty. If you have a boolean sub field type however, that will never be considered empty since 0 could mean false as desired to be displayed. I can't reproduce the issue ultimately or understand what may be missing for you but open to seeing more of an explanation to consider if you want to share please. Also worth considering retesting this against latest version to see if any of this has improved as there were recent code changes since this request was submitted that may have already resolved it for you.

Closing due to no response.

@apmsooner Yes, it's exactly the problem of the table display.

Fixed in dev branch.
