Qfyilyi

I'm trying to knit a rmarkdown file to PDF file which contains kableExtra functions like:

• kable_styling


• column_spec


• add_header_above

However I am always getting the following error:

! Extra alignment tab has been changed to cr.

<template> endtemplate 



l.184 end{tabular}}





pandoc.exe: Error producing PDF

Error: pandoc document conversion failed with error 43

Ejecución interrumpida

One easy example that I am executing is:

```

---

output:

 pdf_document:

   keep_tex: yes

classoption: table

header-includes:

  - usepackage{array}

  - usepackage{float}

  - usepackage{xcolor}

---



```{r results='asis'}

options(kableExtra.latex.load_packages = FALSE)

require(kableExtra)

print(kable(head(cars),"latex")%>%kable_styling(latex_options = c("striped", 

"bordered"))

  %>%column_spec(column=1:2,width = "0.5in") %>%

      kable_styling(c("striped", "bordered"),latex_options = 

"scale_down")%>% add_header_above(c(" "=7,

"Absolute"=1,"Relative"=1,"Absolute"=1,"Relative"=1,

"Absolute"=1,"Relative"=1,"Absolute"=1,"Relative"=1,"Absolute"=1,

"Relative"=1))%>%

add_header_above(c(" "= 1,"Non-weighted"=1,"Weighted"=1,"Non- 

weighted"=1,"Weighted"=1,"Non-weighted"=1,

"Weighted"=1,"Weighted"=2,"Non-weighted"=2,"Weighted"=2,"Non- 

weighted"=2,"Weighted"=2))%>%

add_header_above(c("Theoretical Values"= 1,"First-Order Predicted 

Value"=2,"Second-Order Predicted Value"=2,

"Third-Order Predicted Value"=2,

"Non-linearity 1st Order"=2,"Non-linearity 2nd Order"=4,"Non-linearity 3rd 

Order"=4)))

```

Can anyone help me with this issue?

I would appreciate whatever clue!

You are telling kableExtra not to load the LaTeX packages (why?), so you have to do this yourself. The features you are using require array, float and xcolor with the table option. One difficulty is that fancyvrb v3.0 already loads xcolor with other options. You can circumvent this by supplying table as a class option:

```{r results='asis'}

options(kableExtra.latex.load_packages = FALSE)

require(kableExtra)

print(kable(head(cars),"latex") %>%column_spec(column=1:2,width = "0.5in"))

```



```{r results='asis'} 

print(kable(head(cars),"latex")%>%kable_styling(latex_options = c("striped", "bordered")))
