Thesisdown：加载huxtable包并创建表时，编织到PDF失败

Question

我想在使用thesisdow包创建的文档中使用huxtable包创建表。编织为html可以很好地处理HTML。但是，在装入huxtable之后，一旦包含表格，编织到PDF就会失败，并出现以下错误：

 ! LaTeX Error: Environment threeparttable undefined.

似乎与LaTex软件包在后台发生冲突。在MWE下方，用于thesisdown index.file。有趣的是，在一个简单的markdown文件中，编织成html和PDF的文件都没有问题。由于thesisdown建立在bookdown上，因此当将bookdown文件编织成PDF时，也有可能发生错误。

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摘要：

• 编织为HTML始终有效
• 仅当“ library（huxtable）”之后没有表时，即，当未执行代码块“ pressure-table2”时，编织为PDF才有效

UPDATE：

（（1）如果使用thesisdown，包括@ dash2建议的YAML标头中huxtable所需的LaTex程序包，效果很好。

（（2）但是，如果使用huskydown，则问题仍然存在。

    # Random Test Output - *after* calling "library(huxtable)"

    pressure
    ```

尽管加载LaTex程序包，但编制索引。huskydown的Rmd再次引发错误：

 ! LaTeX Error: Environment threeparttable undefined.

[LaTex软件包是否已被[[huskydown忽略？

Answer 1

@ dash2建议的解决方案：手动包括LaTex软件包

“装有header-includes的LaTex软件包被huskydown忽略了？”-似乎实际上是这种假设。因此，LaTex软件包不能包含在index.Rmd文件的YAML标头中。

huskydown论文模板包括文件“ header-includes”，该文件定义了文档类并提供了多个LaTex软件包。将template.tex所需的所有LaTex软件包手动添加到此文件即可解决此问题：

huxtable
