I found it

Not certain what I'm doing, but I've played with it so much, it was Trial and Error.
Code:
Dim i As Integer, x As Integer, iTbl As Integer, sOthers As String
For i = 1 To ActiveDocument.Tables.Count
If ActiveDocument.Tables(i).Columns.Count > x Then
x = ActiveDocument.Tables(i).Columns.Count
iTbl = i
sOthers = ""
ElseIf ActiveDocument.Tables(i).Columns.Count = x Then
sOthers = sOthers & ""
End If
Next i
MsgBox "The table with the most columns is " & x & " Columns."
On Error GoTo 0
I didn't really need to know about the others, so I've played with it, until I didn't see Red, or an Error message.
OMG Thank you so much.
Million appreciations for your guidance and help.
What I've put, does it makes sense to you both?
