def AfterBindData(e):
    entity = this.View.BillBusinessInfo.GetEntity('FEntity') # FEntity 为单据体标识
    objCollection =this.View.Model.GetEntityDataObject(entity)
    grid =this.View.GetControl('FEntity')
    for index in range(len(objCollection)):
        obj = objCollection[index]
        valDebit = obj["Score"]
        if valDebit is not None :
            grid.SetForecolor("FScore","#FF0000", index);#需要设置字段标识Key

   

效果如图：

特别注意，python非常注意缩进，一定记得保持缩进！！！

不是设置单据体的颜色，是要设置单据体字段标题的颜色

背景色同理，只需要把最后一行改成j即可：

grid.SetBackcolor("FScore","#FFFF00", index);#需要设置字段标识Key

效果如图：
