Change display for one crosstab only

Hello people,

I have one question : is it possible to modify the display of a crosstab ? And only one !

Here the css i want to use for this one crosstab (in this exemple, it will works for all crosstab) :

.sapzencrosstab-HeaderCellDefault  .sapzencrosstab-DataArea, .sapzencrosstab-DimensionHeaderArea, .sapzencrosstab-ColumnHeaderArea

{

  font-size : 10px;

  height : 10px;

}

.sapzencrosstab-DataCellDefault, .sapzencrosstab-HeaderCellDefault{

  height: 10px;

}

.sapzencrosstab-DataCellContentDiv , .sapzencrosstab-RowHeaderArea

{

  font-size : 10px;

}

How can i use this CSS as one CSS Class and apply it for a crosstab without modifying another one ?

Thanks all !
