-## bootstrap了解一下
-如果你从没听过bootstrap的话，你可以去了解一下。简单来说，bootstrap是个开源的CSS库，可以用来很方便地美化HTML页面，也因此在RStudio的产品中被大量使用。你用rmarkdown和shiny生成出来的HTML文档和app都有加载。而这个包的HTML部分也提供了一些借口方便你快速实现一些bootstrap风的表格。
-
-在这份文档中，我们主要使用`mtcars`这个数据的前几列和几行数据来演示。
+## 用`kable`生成HTML表格
+首先要强调一下，`kable`这个function来自于R圈大佬谢益辉的`knitr`包。大致上说，`kable`可以生成三种格式的表格：`HTML`, `LaTeX` 和 `markdown`（默认）。`markdown`作为默认的格式完美契合`rmarkdown`本身，可却因为`markdown`表格本身功能上的限制，在很多情况下达不到我们的要求。因此，当你需要个性化你的表格时，你往往需要先让`kable`先帮你生成一个`HTML`的表格。在这份文档中，我们主要使用`mtcars`这个数据的前几列和几行数据来演示。
 
 ```{r}
-library(knitr)
 library(kableExtra)
 dt <- mtcars[1:5, 1:6]
-```
 
-
-When you are using `kable()`, if you don't specify `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 **define `format` in `kable()`** as either "html" or "latex". *You can also define a global option at the beginning using `options(knitr.table.format = "html")` so you don't repeat the step everytime.* **In this tutorial, I'll still put `format="html"` in the function in case users just want to quickly replicate the results.** 
-
-```{r}
-options(knitr.table.format = "html") 
-## If you don't define format here, you'll need put `format = "html"` in every kable function.
-```
-
-## Basic HTML table
-Basic HTML output of `kable` looks very crude. To the end, it's just a plain HTML table without any love from css.
-```{r}
 kable(dt, "html")
 ```
 
-## Bootstrap theme
-When used on a HTML table, `kable_styling()` will automatically apply twitter bootstrap theme to the table. Now it should looks the same as the original pandoc output (the one when you don't specify `format` in `kable()`) but this time, you are controlling it.
+
+注意，如果你有好几个表格要去生成，与其在每一个kable里定义格式，不如在所有的事情开始之前定义一个全局的设置。这样的话，上面的语句就只需要打`kable(dt)`就可以了。
+
+```{r}
+options(knitr.table.format = "html")

-# Table Styles
-`kable_styling` offers a few other ways to customize the look of a HTML table. 
+# 表格整体风格
+`kable_styling`提供了几种其他的方式来定制表格的整体风格。
 
-## Bootstrap table classes
-If you are familiar with twitter bootstrap, you probably have already known its predefined classes, including `striped`, `bordered`, `hover`, `condensed` and `responsive`. If you are not familiar, no worries, you can take a look at their [documentation site](http://getbootstrap.com/css/#tables) to get a sense of how they look like. All of these options are available here. 
+## Bootstrap的表格`class`
+如果你熟悉bootstrap，那么以下这些css `class`对你一定不陌生：`striped`, `bordered`, `hover`, `condensed` 以及 `responsive`. 如果你不熟悉，你可以看看 [这里](http://getbootstrap.com/css/#tables)。你可以通过`kable_styling`快速地把这些样式应用到你的表格里。比如，下面这个例子就是给表格加上斑马纹和悬浮效果。
 
-For example, to add striped lines (alternative row colors) to your table and you want to highlight the hovered row, you can simply type:
 ```{r}
 kable(dt, "html") %>%
   kable_styling(bootstrap_options = c("striped", "hover"))
 ```
 
-The option `condensed` can also be handy in many cases when you don't want your table to be too large. It has slightly shorter row height.
+有些人觉得默认的bootstrap表格每行都太高了，这时候用上`condensed`会让内容显得更紧凑。
 ```{r}
 kable(dt, "html") %>%
   kable_styling(bootstrap_options = c("striped", "hover", "condensed"))
 ```
 
-Tables with option `responsive` looks the same with others on a large screen. However, on a small screen like phone, they are horizontally scrollable. Please resize your window to see the result.
+`responsive`这选项可以让表格样式随屏幕宽度变化，更适合手机屏。
 ```{r}
 kable(dt, "html") %>%
   kable_styling(bootstrap_options = c("striped", "hover", "condensed", "responsive"))
 ```
 
-## Full width?
-By default, a bootstrap table takes 100% of the width. It is supposed to use together with its grid system to scale the table properly. However, when you are writing a rmarkdown document, you probably don't want to write your own css/or grid. For some small tables with only few columns, a page wide table looks awful. To make it easier, you can specify whether you want the table to have  `full_width` or not in `kable_styling`. By default, `full_width` is set to be `TRUE` for HTML tables (note that for LaTeX, the default is `FALSE` since I don't want to change the "common" looks unless you specified it.)
+## “为啥我的表格这么宽啊？”
+“为啥我的表格这么宽”是一个`rmarkdown`新人常见问题。原因是`bootstrap`把宽度统一订成了100%的容器宽。设计`bootstrap`的人原来想让你用他们的grid system来控制表格的宽度，可是当你在写`rmarkdown`的时候，难道还想即兴来定义一串`<div>`？解决办法如下。
 ```{r}
 kable(dt, "html") %>%
   kable_styling(bootstrap_options = "striped", full_width = F)
 ```
 
-## Position
-Table Position only matters when the table doesn't have `full_width`. You can choose to align the table to `center`, `left` or `right` side of the page
+## 表格位置
+表格在页面中位置也是排版很重要的一块。注意，这只有在表格不是全屏宽的时候才有用（这是当然的啦。
 ```{r}
 kable(dt, "html") %>%
   kable_styling(bootstrap_options = "striped", full_width = F, position = "left")
 ```
 
-Becides these three common options, you can also wrap text around the table using the `float-left` or `float-right` options. 
+除了常见的左中右，你还可以选择`float_left`和`float_right`。
 ```{r}
 kable(dt, "html") %>%
   kable_styling(bootstrap_options = "striped", full_width = F, position = "float_right")
 ```

-# Column / Row Specification
-## Column spec
-When you have a table with lots of explanatory texts, you may want to specified the column width for different column, since the auto adjust in HTML may not work in its best way while basic LaTeX table is really bad at handling text wrapping. Also, sometimes, you may want to highlight a column (e.g. a "Total" column) by making it bold. In these scenario, you can use `column_spec()`. You can find an example below. 
-
-Warning: If you have a super long table, you should be cautious when you use `column_spec` as the xml node modification takes time.
+# 列与行的格式
+## 列
+`column_spec`如其名，可以帮你定义某一列的样式，比如宽度啊，字体颜色啊，加粗，斜体等。列的宽度其实尤为重要，这样你表格的样式不会被一串巨长的文字打乱。

-Similar with `column_spec`, you can define specifications for rows. Currently, you can either bold or italiciz an entire row. Note that, similar with other row-related functions in `kableExtra`, for the position of the target row, you don't need to count in header rows or the group labelling rows.
+## 行

-# Cell/Text Specification
-Function `cell_spec` is introduced in version 0.6.0 of `kableExtra`. Unlike `column_spec` and `row_spec`, **this function is designed to be used before the data.frame gets into the `kable` function**. Comparing with figuring out a list of 2 dimentional index for targeted cells, this design is way easier to learn and use and it fits perfectly well with `dplyr`'s `mutate` and `summarize` functions. With this design, there are two things to be noted:
-* Since `cell_spec` generates raw `HTML` or `LaTeX` code, make sure you remember to put `escape = FALSE` in `kable`. At the same time, you have to escape special symbols including `%` manually by yourself
-* `cell_spec` needs a way to know whether you want `html` or `latex`. You can specify it locally in function or globally via the `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. 
+# 格子的格式
+`cell_spec` 和之前说的两个`spec`不一样，你应该在把你的数据放进`kable`之前使用它。就像如下的例子，`cell_spec`可以很轻易的用在`dplyr`的pipeline里。注意，因为你用`cell_spec`生成的是直接的`HTML`和`LaTeX`，你需要在`kable`里加上`escape = FALSE`。同时，你需要告诉`cell_spec`你到底需要`HTML`还是`LaTeX`。如果你需要大量使用的话，使用全局格式设定会让你好过很多。再说一遍，`options(knitr.table.format = "latex")`。
 
-Currently, `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.

-## Conditional logic
-It is very easy to use `cell_spec` with conditional logic. Here is an example.
+## `cell_spec`和`ifelse`

-## Visualize data with Viridis Color
-This package also comes with a few helper functions, including `spec_color`, `spec_font_size` & `spec_angle`. These functions can rescale continuous variables to certain scales. For example, function `spec_color` would map a continuous variable to any [viridis color palettes](https://CRAN.R-project.org/package=viridisLite). It offers a very visually impactful representation in a tabular format. 
+## 给你的表格加上Viridis Color

-## Text Specification
-If you check the results of `cell_spec`, you will find that this function does nothing more than wrapping the text with appropriate HTML/LaTeX formatting syntax. The result of this function is just a vector of character strings. As a result, when you are writing a `rmarkdown` document or write some text in shiny apps, if you need extra markups other than **bold** or *italic*, you may use this function to `r text_spec("color", color = "red")`, `r text_spec("change font size ", font_size = 16)` or `r text_spec("rotate", angle = 30)` your text.

-# To display the text, type `r text_formatted` outside of the chunk
 ```

-## Tooltip
-It's very easy to add a tooltip to text via `cell_spec`. For example, `text_spec("tooltip", color = "red", tooltip = "Hello World")` will give you something like `r text_spec("Hover over me", color = "red", tooltip = "Hello World")` (you need to wait for a few seconds before your browser renders it). 
+## Tooltip 悬浮提示框
+你可以通过`cell_spec`相对简单地添加悬浮提示框. 举个例子，`text_spec("tooltip", color = "red", tooltip = "Hello World")` 会生成 `r text_spec("Hover over me", color = "red", tooltip = "Hello World")`。注意HTML原生的提示框非常慢，你可能会想用`bootstrap`的javascript版的。如果你想这么做的话，你需要把接下来的这段代码放在你的rmarkdown文本的任何地方。需要注意的是，如果你和这个文档一样使用了这种目录在侧面的格式，你就没办法使用这个功能。原因在于这个和`jqueryui`的`tooltip`互相冲突。这种情况下，你可能会想试试我下面说的`popover`。这两个差不多。

-In a rmarkdown document, you can just drop it outside of any R chunks.

As a result, I can't provide a live demo here. If you want to have a tooltip together with a floating TOC, you should use `popover` which has a very similar effect.

-# Grouped Columns / Rows

-Tables with multi-row headers can be very useful to demonstrate grouped data. To do that, you can pipe your kable object into `add_header_above()`. The header variable is supposed to be a named character with the names as new column names and values as column span. For your convenience, if column span equals to 1, you can ignore the `=1` part so the function below can be written as `add_header_above(c(" ", "Group 1" = 2, "Group 2" = 2, "Group 3" = 2)).

+我们在Word里做表格时，要想表示两个列同属一个类，我们会在这两列的上面再加一行，画条横线，写上名字。基本上`add_header_above`就是做这事的。在使用这个方程时，你需要给他一个**`named vector`**（划重点）。这个`named vector`的本身是column span，而具体的文字则在names里（没看懂我在说啥的，请参考下面的例子）。这样的设计主要是为了方便。

+<p>首先要强调一下，<code>kable</code>这个function来自于R圈大佬谢益辉的<code>knitr</code>包。大致上说，<code>kable</code>可以生成三种格式的表格：<code>HTML</code>, <code>LaTeX</code> 和 <code>markdown</code>（默认）。<code>markdown</code>作为默认的格式完美契合<code>rmarkdown</code>本身，可却因为<code>markdown</code>表格本身功能上的限制，在很多情况下达不到我们的要求。因此，当你需要个性化你的表格时，你往往需要先让<code>kable</code>先帮你生成一个<code>HTML</code>的表格。在这份文档中，我们主要使用<code>mtcars</code>这个数据的前几列和几行数据来演示。</p>
 <pre class="r"><code>library(kableExtra)

-<p>When you are using <code>kable()</code>, if you don’t specify <code>format</code>, 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 <strong>define <code>format</code> in <code>kable()</code></strong> as either “html” or “latex”. <em>You can also define a global option at the beginning using <code>options(knitr.table.format = &quot;html&quot;)</code> so you don’t repeat the step everytime.</em> <strong>In this tutorial, I’ll still put <code>format=&quot;html&quot;</code> in the function in case users just want to quickly replicate the results.</strong></p>

Comparing with figuring out a list of 2 dimentional index for targeted cells, this design is way easier to learn and use and it fits perfectly well with <code>dplyr</code>’s <code>mutate</code> and <code>summarize</code> functions. With this design, there are two things to be noted: * Since <code>cell_spec</code> generates raw <code>HTML</code> or <code>LaTeX</code> code, make sure you remember to put <code>escape = FALSE</code> in <code>kable</code>. At the same time, you have to escape special symbols including <code>%</code> manually by yourself * <code>cell_spec</code> needs a way to know whether you want <code>html</code> or <code>latex</code>. You can specify it locally in function or globally via the <code>options(knitr.table.format = &quot;latex&quot;)</code> method as suggested at the beginning. If you don’t provide anything, this function will output as HTML by default.</p>

For example, <code>text_spec(&quot;tooltip&quot;, color = &quot;red&quot;, tooltip = &quot;Hello World&quot;)</code> will give you something like <span style="     color: red;TRUE" data-toggle="tooltip" data-placement="right" title="Hello World">Hover over me</span> (you need to wait for a few seconds before your browser renders it).</p>
-<p>Note that the original browser-based tooltip is slow. If you want to have a faster response, you may want to initialize bootstrap’s tooltip by putting the following HTML code on the page.</p>
+<div id="tooltip-" class="section level2">
+<h2>Tooltip 悬浮提示框</h2>
+<p>你可以通过<code>cell_spec</code>相对简单地添加悬浮提示框. 举个例子，<code>text_spec(&quot;tooltip&quot;, color = &quot;red&quot;, tooltip = &quot;Hello World&quot;)</code> 会生成 <span style="     color: red;" data-toggle="tooltip" data-placement="right" title="Hello World">Hover over me</span>。注意HTML原生的提示框非常慢，你可能会想用<code>bootstrap</code>的javascript版的。如果你想这么做的话，你需要把接下来的这段代码放在你的rmarkdown文本的任何地方。需要注意的是，如果你和这个文档一样使用了这种目录在侧面的格式，你就没办法使用这个功能。原因在于这个和<code>jqueryui</code>的<code>tooltip</code>互相冲突。这种情况下，你可能会想试试我下面说的<code>popover</code>。这两个差不多。</p>
 <pre><code>&lt;script&gt;
 $(document).ready(function(){
     $('[data-toggle=&quot;tooltip&quot;]').tooltip(); 
 });
 &lt;/script&gt;</code></pre>
-<p>In a rmarkdown document, you can just drop it outside of any R chunks. Unfortunately however, for rmarkdown pages with a <strong>floating TOC</strong> (like this page), you can’t use bootstrap tooltips because there is a conflict in namespace between Bootstrap and JQueryUI (tocify.js). As a result, I can’t provide a live demo here. If you want to have a tooltip together with a floating TOC, you should use <code>popover</code> which has a very similar effect.</p>

-<h2>Popover Message</h2>
-<p>The popover message looks very similar with tooltip but it can hold more contents. Unlike tooltip which can minimally work without you manually enable that module, you <strong>have to</strong> enable the <code>popover</code> module to get it work. The upper side is that there is no conflict between Bootstrap &amp; JQueryUI this time, you can use it without any concern.</p>

-<h2>Add header rows to group columns</h2>
-<p>Tables with multi-row headers can be very useful to demonstrate grouped data. To do that, you can pipe your kable object into <code>add_header_above()</code>. The header variable is supposed to be a named character with the names as new column names and values as column span. For your convenience, if column span equals to 1, you can ignore the <code>=1</code> part so the function below can be written as `add_header_above(c(&quot; “,”Group 1&quot; = 2, “Group 2” = 2, “Group 3” = 2)).</p>
