Duplicated rows with \vphantom issue again

[philturk]

Hi Hao, this question touches upon the same topic raised in Issues #161 and #145. Is there any way to stop kableExtra from using \vphantom space in the raw LaTeX code to "identify" a duplicated row in a table? I am not sure you need yet another reproducible example, but here you go:

```{r}
library(kableExtra)

toydata <- tibble(Var1 = c(1,2,2,3), Var2 = c("My stuff", "Hello world", "Hello world", "My stuff"))

kable(toydata, "latex", booktabs = T, align = "cr") %>%
  row_spec(0, bold = T, angle = 0) %>%  
  add_header_above(c("Toy Data" = 2)) %>%
  kable_styling(latex_options = c("striped"))
```

Upon execution, this produces LaTeX code containing extra whitespace (i.e., \vphantom{1}) between 'Hello' and 'world' in the second row, but none in the duplicate row immediately following. Of course, while I am grateful for your package, the pdf output does not suit my own personal taste :)

Best,

-- Phil

Hi, Phil, thanks for reporting this! \vphantom suppose to have zero space width. After reviewing my code, I realized that I accepted an PR from someone else a while ago which inserted an extra space after \vphantom. Now this behavior has been addressed. 👍

Thank you. I'm looking forward to trying it.
