+The goal of \texttt{kableExtra} is to help you build common complex
+tables and manipulate table styles. It imports the pipe
+\texttt{\%\textgreater{}\%} symbol from \texttt{magrittr} and verbalizes
+all the functions, so basically you can add ``layers'' to a kable output
+in a way that is similar with \texttt{ggplot2} and \texttt{plotly}.

+
+When you are using \texttt{kable()}, if you don't specify
+\texttt{format}, by default it will generate a markdown table and let
+pandoc handle the conversion from markdown to HTML/PDF. This is the most
+favorable approach to render most simple tables as it is format
+independent. If you switch from HTML to pdf, you basically don't need to
+change anything in your code. However, markdown doesn't support complex
+table. For example, if you want to have a double-row header table,
+markdown just cannot provide you the functionality you need. As a
+result, when you have such a need, you should \textbf{define
+\texttt{format} in \texttt{kable()}} as either ``html'' or ``latex''.
+\emph{You can also define a global option at the beginning using
+\texttt{options(knitr.table.format\ =\ "latex")} so you don't repeat the
+step every time.} \textbf{In this tutorial, I'll still put
+format=``latex'' in the function in case users just want to quickly
+replicate the results. In practice, you don't need to define those
+formats.}
+
+\textbf{Starting from \texttt{kableExtra} 0.9.0}, when you load this
+package (\texttt{library(kableExtra)}),
+\textcolor{red}{\textbf{it will automatically set up the global option 'knitr.table.format' based on your current environment}}.
+Unless you are rendering a PDF, \texttt{kableExtra} will try to render a
+HTML table for you. \textbf{You no longer need to manually set either
+the global option or the \texttt{format} option in each \texttt{kable()}
+function}. I'm still including the explanation above here in this
+vignette so you can understand what is going on behind the scene. Note
+that this is only an global option. You can manually set any format in
+\texttt{kable()} whenever you want. I just hope you can enjoy a peace of
+mind in most of your time.
+
+You can disable this behavior by setting
+\texttt{options(kableExtra.auto\_format\ =\ FALSE)} before you load
+\texttt{kableExtra}.

+If you are using a recent version of rmarkdown, you are recommended to
+load this package entirely via \texttt{library(kableExtra)} or
+\texttt{require(kableExtra)} because this package will load all
+necessary LaTeX packages, such as \texttt{booktabs} or
+\texttt{multirow}, for you automatically. Note that, if you are calling
+functions from \texttt{kableExtra} via
+\texttt{kableExtra::kable\_styling()} or if you put
+\texttt{library(kableExtra)} in a separate R file that is
+\textbf{sourced} by the rmarkdown document, these packages won't be
+loaded. Furthermore, you can suppress this auto-loading behavior by
+setting a global option \texttt{kableExtra.latex.load\_packages} to be
+\texttt{FALSE} before you load \texttt{kableExtra}.

+If you are using R Sweave, beamer, R package vignette template, tufte or

+\texttt{kable\_styling} in LaTeX uses the same syntax and structure as
+\texttt{kable\_styling} in HTML. However, instead of
+\texttt{bootstrap\_options}, you should specify \texttt{latex\_options}
+instead.
+
+\hypertarget{latex-options}{%

+
+Similar with \texttt{bootstap\_options}, \texttt{latex\_options} is also

+
+\hypertarget{striped}{%
+\subsubsection{Striped}\label{striped}}
+
+Even though in the LaTeX world, people usually call it
+\texttt{alternative\ row\ colors} but here I'm using its bootstrap name
+for consistency. Note that to make it happen, LaTeX package
+\texttt{xcolor} is required to be loaded. In an environment like
+rmarkdown::pdf\_document (rmarkdown 1.4.0 +), \texttt{kable\_styling}
+will load it automatically if \texttt{striped} is enabled. However, in
+other cases, you probably need to import that package by yourself.

+If you find \texttt{hold\_position} is not powerful enough to literally
+PIN your table in the exact position, you may want to use
+\texttt{HOLD\_position}, which is a more powerful version of this
+feature. For those who are familiar with LaTeX, \texttt{hold\_position}

+When you have a wide table that will normally go out of the page, and

+\texttt{scale\_down} option here. Note that, if your table is too small,
+it will also scale up your table. It was named in this way only because
+scaling up isn't very useful in most cases.

+\texttt{scale\_down}, it won't change your font size. You can use
+\texttt{column\_spec}, which will be explained later, together with
+\texttt{full\_width} to achieve the best result.

+
+Function \texttt{cell\_spec} is introduced in version 0.6.0 of
+\texttt{kableExtra}. Unlike \texttt{column\_spec} and
+\texttt{row\_spec}, \textbf{this function is designed to be used before
+the data.frame gets into the \texttt{kable} function}. Comparing with
+figuring out a list of 2 dimensional indexes for targeted cells, this
+design is way easier to learn and use, and it fits perfectly well with
+\texttt{dplyr}'s \texttt{mutate} and \texttt{summarize} functions. With
+this design, there are two things to be noted: * Since
+\texttt{cell\_spec} generates raw \texttt{HTML} or \texttt{LaTeX} code,
+make sure you remember to put \texttt{escape\ =\ FALSE} in
+\texttt{kable}. At the same time, you have to escape special symbols
+including \texttt{\%} manually by yourself * \texttt{cell\_spec} needs a
+way to know whether you want \texttt{html} or \texttt{latex}. You can
+specify it locally in function or globally via the
+\texttt{options(knitr.table.format\ =\ "latex")} method as suggested at
+the beginning. If you don't provide anything, this function will output
+as HTML by default.
+
+Currently, \texttt{cell\_spec} supports features including bold, italic,
+monospace, text color, background color, align, font size \& rotation
+angle. More features may be added in the future. Please see function
+documentations as reference.

+If you check the results of \texttt{cell\_spec}, you will find that this

+Function \texttt{group\_rows} is great for showing simple structural
+information on rows but sometimes people may need to show structural
+information with multiple layers. When it happens, you may consider
+using \texttt{collapse\_rows} instead, which will put repeating cells in
+columns into multi-row cells.
+
+In LaTeX, \texttt{collapse\_rows} adds some extra hlines to help
+differentiate groups. You can customize this behavior using the
+\texttt{latex\_hline} argument. You can choose from \texttt{full}
+(default), \texttt{major} and \texttt{none}. Vertical alignment of cells
+is controlled by the \texttt{valign} option. You can choose from
+``top'', ``middle''(default) and ``bottom''. Be cautious that the
+vertical alignment option was only introduced in multirow in 2016. If
+you are using a legacy LaTeX distribution, you will run into trouble if
+you set \texttt{valign} to be either ``top'' or ``bottom''.

+\begin{quote}
+Now it's recommended to use the new \texttt{footnote} function instead
+of \texttt{add\_footnote} to make table footnotes.
+\end{quote}
+
+Documentations for \texttt{add\_footnote} can be found
+\href{http://haozhu233.github.io/kableExtra/legacy_features\#add_footnote}{here}.
+
+There are four notation systems in \texttt{footnote}, namely
+\texttt{general}, \texttt{number}, \texttt{alphabet} and
+\texttt{symbol}. The last three types of footnotes will be labeled with
+corresponding marks while \texttt{general} won't be labeled. You can
+pick any one of these systems or choose to display them all for
+fulfilling the APA table footnotes requirements.

+You can also specify title for each category by using the

+If you need to add footnote marks in a table, you need to do it manually
+(no fancy) using \texttt{footnote\_marker\_***()}. Remember that similar
+with \texttt{cell\_spec}, you need to tell this function whether you
+want it to do it in \texttt{HTML} (default) or \texttt{LaTeX}. You can
+set it for all using the \texttt{knitr.table.format} global option.
+Also, if you have ever used \texttt{footnote\_marker\_***()}, you need
+to put \texttt{escape\ =\ F} in your \texttt{kable} function to avoid
+escaping of special characters. Note that if you want to use these
+\texttt{footnote\_marker} functions in \texttt{kableExtra} functions
+like \texttt{group\_rows} (for the row label) or
+\texttt{add\_header\_above}, you need to set
+\texttt{double\_escape\ =\ T} and \texttt{escape\ =\ F} in those
+functions. I'm trying to find other ways around. Please let me know if
+you have a good idea and are willing to contribute.

+
+Unlike in HTML, where you can use \texttt{\textless{}br\textgreater{}}
+at any time, in LaTeX, it's actually quite difficult to make a linebreak
+in a table. Therefore I created the \texttt{linebreak} function to
+facilitate this process. Please see the
+\href{http://haozhu233.github.io/kableExtra/best_practice_for_newline_in_latex_table.pdf}{Best
+Practice for Newline in LaTeX Table} for details.
