Hi Paul
You could try this macro approach - run it on Normal.dotm and save the template. It will show "No Style". You can create your own Table Styles.
Sub jec_HideAllTableStylesInDoc()Dim s As Style For Each s In ActiveDocument.Styles If s.Type = wdStyleTypeTable Then s.Visibility = True s.UnhideWhenUsed = True End If Next s End Sub
