Vertical Align in Cell for Latex

[matton2]

Hello and thank you for this package!!

I would like to vertically align my text in the cell without using collapse_row since it is just a single cell.

The code below creates a table where the first column is top vertical aligned; it would be great if I could choose to have it vertical aligned 'middle'.

Thank for any help you can provide,
matt

library(kableExtra)
knitr::opts_chunk$set(echo = TRUE)
```

```{r, include=FALSE}
testDataFrame <- data.frame(col1 = c('something', 'something'), col2 = c('something that is much longer and i would like the first col to be veritcal aligned, this probably needs to be even longer to get my point across', 'something that is much longer and i would like the first col to be veritcal aligned'), stringsAsFactors = FALSE)
```

```{r}

kable(
  testDataFrame,
  format = 'latex',
  longtable = T,
  align = 'c'
) %>% 
  kable_styling(latex_options = c("repeat_header"), repeat_header_text = "Previous Table Continued", font_size = 9) %>% 
  column_spec(1, width = "8em", ) %>% 
  column_spec(c(-1), paste0(45/round(NCOL(testDataFrame),1),"em")) %>% 
  row_spec(0, bold = TRUE) 

```

@matton2 Just added a new option latex_valign for column_spec. However I don't fully understand how it works. It seems that the only way to middle align the first column is to specify "m" at the second column. 🧐

If anyone can find out a fix, that would be great!

kable(
  testDataFrame,
  format = 'latex',
  longtable = T,
  align = 'c') %>% 
  kable_styling(latex_options = c("repeat_header"), repeat_header_text = "Previous Table Continued", font_size = 9) %>% 
  column_spec(1, width = "8em", bold = T) %>% 
  column_spec(2, "10em", latex_valign = "m") %>% 
  row_spec(0, bold = TRUE)
