Hi again For your information, I have found another workaround : by setting the "special multicolumn alignment " of the "empty" cell just before my subcaption to anything but empty, I get the correct result. This is still a workaround, because doing the same in others rows deletes the corresponding borders, even if the following cells have their left border set. In any case, I can live with that. Once again, this is to help you, not a requirement from a "client".
