在表格环境中插入了ifnum和missing}

Question

我正在尝试编写预算提案，并且正在使用计数器来控制每件商品的数量和价格。我还创建了一个表，并使用\ ifnum来控制是否应将该项目包括在提案中（仅当数量大于0时）。

我在第一个\ ifnum中插入了“ Missing}”，但是我似乎找不到为什么。我缺少明显的东西吗？

还有一个问题，当一个项目的数量为0时，尽管在\ ifnum里面应该为假，但在生成表时仍会包括该行（只是忽略第一个单元格）。这还会在第二个\ ifnum上提示“额外的\ fi”错误。

这是下面的代码和它生成的表：

Answer 1

基于https://tex.stackexchange.com/a/131284/36296的小技巧，将filter的“＆”号隐藏在表中

另外

• 每行周围的组都需要删除

• 空行已删除

• 在行中移动arrayformula，否则它将开始一个新单元格
