The code you posted shows nothing about "omitting" tables.
If you want to remove "Table" captions and those captions stand alone in its parent paragraphs, you can use:
Code:
Sub ScratchMacro()
'A basic Word macro coded by Greg Maxey
Dim oFld As Field
For Each oFld In ActiveDocument.Fields
If oFld.Type = wdFieldSequence Then
'See if it is a Table caption sequence field
If InStr(oFld.Code, "Table") <> 0 Then
oFld.Code.Paragraphs(1).Range.Delete
End If
End If
Next oFld
lbl_Exit:
Exit Sub
End Sub
