[client] Make table background use look and feel

The table was opaque and therefore did not adhere to the look and feel.
Table and TableCellRenderer now set to non opaque for non selected
rows which lets the background through. Selected rows still should be
opaque to show a different background indicating selection (e.g. blue).
