Thesisdown：加载 huxtable 包和创建表时编织到 PDF 失败

Question

我想在使用 thesisdow 创建的文档中使用 huxtable 包创建 tables包裹。编织到 html 与 HTML 配合得很好。但是，一旦在加载 huxtable:

后包含 table，编织 PDF 就会失败并出现以下错误

 ! LaTeX Error: Environment threeparttable undefined.

后台似乎与 LaTex 包发生冲突。低于论文的 MWE index.file。有趣的是，在一个简单的 markdown 文件中，编织到 html 和 PDF 都没有问题。由于thesisdown是建立在bookdown上的，所以在将bookdown文件编织成PDF时也有可能出现这个错误。

index.Rmd

    ---
    knit: "bookdown::render_book"
    site: bookdown::bookdown_site
    output: 
     thesisdown::thesis_pdf: default
      # thesisdown::thesis_gitbook: default
    ---

    ```{r include_packages, include = FALSE}
    # Ensure that the thesisdown package is installed and loaded
    if(!require(devtools))
      install.packages("devtools", repos = "http://cran.rstudio.com")
    if(!require(thesisdown))
      devtools::install_github("ismayc/thesisdown")
    library(thesisdown)
    ```

    # Random Test Output - *before* calling "library(huxtable)"
    a table with pressure data
    ```{r pressure-table, echo=FALSE}
    pressure
    ```

    ```{r echo=FALSE}
    library(huxtable)
    ```

    # Random Test Output - *after* calling "library(huxtable)"
    a table with pressure data
    ```{r pressure-table2, echo=FALSE}
    pressure
    ```

MWE 总结：

编织到 HTML 总是有效
仅当 "library(huxtable)" 之后没有 table 时，编织到 PDF 才有效，即当代码块 "pressure-table2" 未执行时

更新：

(1) 如果使用 thesisdown，将 huxtable 所需的 LaTex 包包含在 YAML-header 中，如 @dash2 所建议的，效果很好。

(2) 但是，如果使用 huskydown，不幸的是问题仍然存在。

    a table with pressure data
    ```{r pressure-table, echo=FALSE}

尽管加载了 LaTex 包，为 huskydown 编织 index.Rmd 再次抛出错误：

 ! LaTeX Error: Environment threeparttable undefined.

加载了 header-includes 的任何 LaTex 包是否可能被 huskydown 忽略？

Answer 1

@dash2 推荐的解决方案：手动包含 LaTex 包

"LaTex packages loaded with header-includes ignored by huskydown?"——看来这个推定实际上是这样的。因此，LaTex 包不能包含在 index.Rmd 文件的 YAML header 中。

huskydown 论文模板包含文件“template.tex”，它定义了文档类和几个 LaTex 包的来源。将 huxtable 所需的所有 LaTex 包手动添加到此文件可解决问题：

 %-------------------------------
 % Huxtable
 %-------------------------------
 % load LaTex packages needed for huxtable 
 \usepackage{array}
 \usepackage{caption}
 \usepackage{graphicx}
 \usepackage{siunitx}
 \usepackage{colortbl}
 \usepackage{multirow}
 \usepackage{hhline}
 \usepackage{calc}
 \usepackage{tabularx}
 \usepackage{tabulary}
 \usepackage{threeparttable}
 \usepackage{wrapfig}
