- *  If defined, the <code>alternatingRowColorsBackground</code>
- *  skin part is used to render row backgrounds whose

- *  in the array value of this style.
+ *  If the <code>alternatingRowColors</code> style is specified,

+ *  in the DataGridSkin class.   
+ *  If you want to specify the background for each row, then 
+ *  initialize the <code>rowBackground</code> skin part directly.</p>
