Background color for column does not work when using full_width

[ghost]

A column in a table should have a background color. When using full_width = TRUE the background color does not appear. As you can see in the output the cells are marked with \cellcolor{green} but in the pdf output the column is not green. Also I can see in the output that the first row of the colored column has not this tag \cellcolor{green}, which will be most likely the next problem. When the full_width = TRUE is removed the column gets coloured but not for the first row (as expected).

```{r}
library(dplyr)
data(mtcars)
temp2 <- mtcars[1:5, 1:3]
```
```{r, results='asis'}
cat(
  kableExtra::kbl(
    x = temp2,
    format = "latex",
    digits = 2,
    col.names = NULL,
    booktabs = TRUE,
    position = "h",
    toprule = NULL,
    bottomrule = NULL,
    linesep = ""
  ) %>%
    kableExtra::kable_styling(full_width = TRUE) %>%
    kableExtra::column_spec(column = 2, background = "green") %>%
    kableExtra::row_spec(row = nrow(temp2) - 2, hline_after = TRUE) %>%
    kableExtra::row_spec(row = nrow(temp2) - 1, bold = TRUE, extra_latex_after = "\\hline \\hline")
)
```

So glad to see this issue! It seems full_width and stripes or cell background edits don't work well together.

I found the same problem with full_width and striped rows... Was going crazy trying to add the stripes. They only appear when kable_styling(full_width = F).

Strangely, something like: row_spec(seq(1,nrow(data_prospective),2), **color**="red") works, paired with kable_styling (full_width = T) but row_spec(seq(1,nrow(data_prospective),2), **background**="red") doesn't

This has stripes showing when rendered with pdf:

data_prospective %>% 
  kbl(., booktabs = T, longtable = T) %>% 
  kable_styling(latex_options = c("striped","repeat_header"), 
                                  full_width = F, 
                                  font_size = 8) %>% 
  column_spec(column = 4, width = "5cm")

The same issue of incompatibility between kable_styling and column_spec happens for me. A somewhat simplified example is the following:

---
title: "DEMO"
output:
  pdf_document:
    latex_engine: xelatex
---

```{r, echo=FALSE}
library(kableExtra)
options(knitr.table.format = "latex")

kbl(mtcars[1:7, ], align = "c", booktabs = TRUE, linesep = "") %>%
  kable_styling(latex_options = c("striped", "HOLD_position"), full_width = TRUE) %>%
  column_spec(1, width = "4cm")

This produces a table without the striping:

The striping is correctly present when full_width = FALSE.

I believe that this is an upstream problem with the tabu package in LaTeX:
