SpanLabel seems to have 1 character of left padding. I've derived my own selector from SpanLabel and set padding/margin to zero, but there still seem to be left padding. The screen shot is a 3x2 TableLayout container. The description field is a SpanLabel, all the others a Label.

You can see the "4" and "$" line up vertically, but the text in the description doesn't.
