Unexpected behaviours when making tables for copernicus articles

Bắt đầu từ entry point của article template Copernicus và render example được cung cấp bằng bookdown::pdf_book, sau đó kiểm tra .tex được tạo quanh \toprule. Kiểm tra thiết lập package LaTeX của template và cách xử lý các tham chiếu bảng cũng như trích dẫn. Hoàn tất khi PDF biên dịch được với booktabs và cả tham chiếu bảng lẫn trích dẫn @Dirac1953888 đều được render chính xác.

I want to make a simple table (where booktabs=TRUE) in a copernicus article. When I knit the following copernicus article (using the template provided by the package) to pdf_book

  \section{Figures and tables in appendices}
  \subsection{Option 1}
  If you sorted all figures and tables into the sections of the text, please also sort the appendix figures and appendix tables into the respective appendix sections.
  They will be correctly named automatically.
  \subsection{Option 2}
  If you put all figures after the reference list, please insert appendix tables and figures after the normal tables and figures.
  
  `\appendixfigures` needs to be added in front of appendix figures
  `\appendixtables` needs to be added in front of appendix tables
  
  Please add `\clearpage` between each table and/or figure. Further guidelines on figures and tables can be found below.
  Regarding figures and tables in appendices, the following two options are possible depending on your general handling of figures and tables in the manuscript environment:
  To rename them correctly to A1, A2, etc., please add the following commands in front of them:

  bookdown::pdf_book:
    base_format: rticles::copernicus_article # for using bookdown features like \@ref()

\introduction[Introduction]

See Table \@ref(tab:t)

```{r t, echo=FALSE}
df = mtcars[1:3, 1:3]
df$ref = "@Dirac1953888"
knitr::kable(df, booktabs = TRUE)
```

I get the following error:

tlmgr update --all --self
tlmgr: package repository https://mirror.easyname.at/ctan/systems/texlive/tlnet (verified)
tlmgr install: package already present: hyperref
! Undefined control sequence.
l.142 \toprule

Error: LaTeX failed to compile t.tex. See https://yihui.org/tinytex/r/#debugging for debugging tips. See t.log for more info.
Execution halted

Interestingly, when I do not use booktabs (which I need to):

```{r t, echo=FALSE}
df = mtcars[1:3, 1:3]
df$ref = "@Dirac1953888"
knitr::kable(df, booktabs = FALSE)
```

I get:

So, rendering of the document seems to work, but there are 2 problems:

• Table referencing does not work
• Citation (@Dirac1953888) which is included in the sample.bib file (provided by the copernicus template) does not properly show up in the "ref" column of the table
