在MSWord表格单元格中使用公式

Question

我在这里结束了我的智慧。我一直在尝试在Microsoft Word 2013 Table上为几个单元格自动计算。我首先尝试创建VBA脚本并且它有效，但我需要在保护模式下使用模板，这使得VBA脚本无法使用！所以我尝试在单元格中添加一个公式，但我意识到如果单元格没有任何值，则输出0而不是空白单元格。如何输出空白单元而不是0？

这是我的公式代码： = PRODUCT（R8C9，R8C1，R8C6）

= SUM（R8C10，R9C10，R10C10，R11C10，R12C10，R13C10，R14C10，R15C10，R16C10，R17C10，R18C10，R19C10，R20C10，R21C10，R22C10，R23C10，R24C10，R25C10，R26C10，R27C10，R28C10，R29C10， R30C10，R32C3）

不可用的VBA代码
