Question

我认为我的问题很简单，可以在没有MRE的情况下回答。这是抛出错误的代码：

DSP %>%
kable(format = "latex",
        digits = 2,
        booktabs = T,
        format.args = list(big.mark = ',')) %>%
  kable_styling(font_size = 9,latex_options = c("striped", "scale_down")) %>%
  column_spec(1, bold = TRUE) %>%
  column_spec(10, bold = TRUE) %>%
  row_spec(nrow(DSP), bold = T)

我在RMarkdown文件中运行它，我在FOR循环中执行，i = 50.换句话说，数据帧DSP重新生成50次，每次它有不同的数量行。 DSP总是有10列。

我想在最后一行加粗。

对于i = 1，nrows = 14.没问题。对于i = 2，nrows = 10.没问题。对于i = 3，nrows = 9.我得到了这个：

4: Removed 22 rows containing missing values (position_stack). 
5: Removed 5 rows containing missing values (position_stack). 
6: Removed 8 rows containing missing values (position_stack).

如果我然后将nrow(DSP)替换为数字9并调用render()语句，它仍会失败，但会显示不同的错误消息：

有谁知道为什么会这样？甚至更好，我如何解决它？

谢谢！

我认为尝试分解您的管道并确定问题的来源是一个好习惯。我有同样的问题，在我的情况下，它来自当我意外格式化不存在的列时kableExtra::column_spec()。

当您收到来自LaTex的错误消息时，这表示格式化时出现问题，并且在哪里并不总是非常直观。您的管道从数据集开始，并通过每个步骤中的kable和kableExtra函数向数据添加一些乳胶标记。如果您确定哪个步骤导致问题，您通常可以轻松找到原因。
