+> **Key Update:** In the latest version of this package (1.2+), we provide a wrapper funciton `kbl` to the original `kable` function with detailed documentation of all the hidden html/latex options. It also does auto-formatting check in every function call instead of relying on the global environement variable. As a result, it also solves an issue for multi-format R Markdown documents. I encourage you start to use the new `kbl` function for all its convenience but the support for the original `kable` function is still there. In this doc, we will use `kbl` instead of `kable`.

 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) %>%
+kbl(dt) %>%
   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.
 ```{r}
-kable(dt) %>%
+kbl(dt) %>%
   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.
 ```{r}

 ## 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.)
 ```{r}
-kable(dt) %>%
+kbl(dt) %>%
   kable_paper(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
 ```{r}
-kable(dt) %>%
+kbl(dt) %>%
   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. 
 ```{r}

+kbl(dt) %>%
   kable_styling(bootstrap_options = "striped", full_width = F, position = "float_right")

 ## Add header rows to group columns
 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)).

 ## Group rows via labeling
 Sometimes we want a few rows of the table being grouped together. They might be items under the same topic (e.g., animals in one species) or just different data groups for a categorical variable (e.g., age < 40, age > 40). With the function `group_rows()`/`pack_rows()` in `kableExtra`, this kind of task can be completed in one line. Please see the example below. Note that when you count for the start/end rows of the group, you don't need to count for the header rows nor other group label rows.

-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 = "latex")` so you don't repeat the step every time.* **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.**
+> **Key Update:** In the latest version of this package (1.2+), we provide a wrapper funciton `kbl` to the original `kable` function with detailed documentation of all the hidden html/latex options. It also does auto-formatting check in every function call instead of relying on the global environement variable. As a result, it also solves an issue for multi-format R Markdown documents. I encourage you start to use the new `kbl` function for all its convenience but the support for the original `kable` function is still there. In this doc, we will use `kbl` instead of `kable`.

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.

 ### Striped
 Even though in the LaTeX world, people usually call it `alternative row colors` but here I'm using its bootstrap name for consistency. Note that to make it happen, LaTeX package `xcolor` is required to be loaded. In an environment like rmarkdown::pdf_document (rmarkdown 1.4.0 +), `kable_styling` will load it automatically if `striped` is enabled. However, in other cases, you probably need to import that package by yourself.

-kable(dt, "latex", booktabs = T) %>%
+kbl(dt, booktabs = T) %>%
   kable_styling(latex_options = "striped")

 You can also specify which rows you want to striped on via `stripe_index`. In most case, you might want to turn off the default 5 rows + a space setting in `knitr::kable()` by setting `linesep = ""`. See this SO answer for details. https://stackoverflow.com/questions/45409750/get-rid-of-addlinespace-in-kable.

 Besides these three common options, you can also wrap text around the table using the `float-left` or `float-right` options. Note that, like `striped`, this feature will load another non-default LaTeX package `wrapfig` which requires rmarkdown 1.4.0 +. If you rmarkdown version < 1.4.0, you need to load the package through a customed LaTeX template file.

 ## Add header rows to group columns
 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)).

   add_header_above(c(" " = 1, "Group 1" = 2, "Group 2" = 2, "Group 3" = 2))
 ```
 
 In fact, if you want to add another row of header on top, please feel free to do so. Also, since kableExtra 0.3.0, you can specify `bold` & `italic` as you do in `row_spec()`.

 ## Group rows via labeling
 Sometimes we want a few rows of the table being grouped together. They might be items under the same topic (e.g., animals in one species) or just different data groups for a categorical variable (e.g., age < 40, age > 40). With the function `pack_rows`/`group_rows()` in `kableExtra`, this kind of task can be completed in one line. Please see the example below. Note that when you count for the start/end rows of the group, you don't need to count for the header rows nor other group label rows. You only need to think about the row numbers in the "original R dataframe".

 If you prefer to build multiple groups in one step, you can use the short-hand `index` option. Basically, you can use it in the same way as you use `add_header_above`.
