Basically something like this:
Code:
Sub ScratchMacro()
'A basic Word macro coded by Greg Maxey
Dim oRow As Word.Row
If Selection.Information(wdWithInTable) Then
Selection.Collapse wdCollapseStart
Set oRow = Selection.Rows(1)
oRow.Cells(1).Range.Text = Format(Now, "hh:mm:ss")
oRow.Cells(2).Range.Text = Format(Now, "dd-MMM-yy")
End If
End Sub
