表中缺少 } 错误

Question

使用 rmarkdown 编译 pdf 文档中的 longtable 时，我收到缺少 } 的错误。表格编织成 html，所以我认为问题出在正在生成的 latex 上，我无法确定为什么}需要 a。这是错误：

! Missing } inserted.
<inserted text>

                        & 49 & 6647 & 4.2 & Also measured risk factors over ...

这是 .tex 输出：

Answer 1

你有 \cellcolor{white}{HbA1C (>8%)

它应该是\cellcolor{white}{HbA1C (>8\%)，因为百分号强制 TeX 忽略该行其余部分的所有内容，在本例中是结尾的}。
