df_child确切的公式是什么GrossCPP（家长）=TotalShare/100*TotalGrossCPP（孩子）+（1-TotalShare/100）*TotalGrossCPM（孩子）
？@StéphaneLaurent，很抱歉公式不清楚。有两个公式；一个用于总CPP（父项）
和一个用于总CPP（父项）
<代码>总CPP（父项）=∑（日部分份额/100）*总CPP（子项）
Gross CPM（parent）=∑（daypart share/100）*Gross CPM（child）
我尝试了您的解决方案，当我去扩展子表时，它会短暂地显示出来，但很快就会隐藏起来，而我没有点击-
按钮来隐藏它。@TimothyMcwilliams您复制粘贴了我的代码（并更改了路径
变量）了吗？没有变化？我复制的唯一代码是回调
块。我想知道为什么这对我来说不起作用。我已经把它隔离到新计算的位置，我所做的只是注释掉新的块，子表保持不变。你认为这是压痕问题吗？@TimothyMcwilliams不，压痕没有效果。如果你复制我所有的代码，它能工作吗？
