The macro recorder won't provide what you need. The required macro might look like:
Code:
Sub Demo()
Application.ScreenUpdating = False
Dim i As Long
With ActiveDocument
For i = 1 To .InlineShapes.Count
With .InlineShapes(i)
If .Range.Information(wdWithInTable) = True Then
.Range.Cells(1).Width = .Width
End If
End With
Next
End With
Application.ScreenUpdating = True
End Sub
