Table title with kableExtra

Question

I want to include a title for the table and the correct names for the columns. How can I do it with the function kableExtra?

kable(tab[211:220,]) %>%
  kable_styling(bootstrap_options = c("striped", "hover"))
```[enter image description here][1]

Answer 1

You can add a title using the caption argument and change the column names using the col.names argument, both of which are options when you call kable. This is before you even need kableExtra.

library(kableExtra)

kable(head(iris), format = "html", caption = "Title of the table", 
col.names = c("sepal_length", "sepal_width", "petal_length", "petal_width", "species")) %>% 
    kable_styling(bootstrap_options = c("striped", "hover"))

This returns the following HTML, or shows you a HTML preview if you are using RStudio.

<table class="table table-striped table-hover" style="margin-left: auto; margin-right: auto;">
<caption>Title of the table</caption>
 <thead>
  <tr>
   <th style="text-align:right;"> sepal_length </th>
   <th style="text-align:right;"> sepal_width </th>
   <th style="text-align:right;"> petal_length </th>
   <th style="text-align:right;"> petal_width </th>
   <th style="text-align:left;"> species </th>
  </tr>
 </thead>
<tbody>
  <tr>
   <td style="text-align:right;"> 5.1 </td>
   <td style="text-align:right;"> 3.5 </td>
   <td style="text-align:right;"> 1.4 </td>
   <td style="text-align:right;"> 0.2 </td>
   <td style="text-align:left;"> setosa </td>
  </tr>
  <tr>
   <td style="text-align:right;"> 4.9 </td>
   <td style="text-align:right;"> 3.0 </td>
   <td style="text-align:right;"> 1.4 </td>
   <td style="text-align:right;"> 0.2 </td>
   <td style="text-align:left;"> setosa </td>
  </tr>
  <tr>
   <td style="text-align:right;"> 4.7 </td>
   <td style="text-align:right;"> 3.2 </td>
   <td style="text-align:right;"> 1.3 </td>
   <td style="text-align:right;"> 0.2 </td>
   <td style="text-align:left;"> setosa </td>
  </tr>
  <tr>
   <td style="text-align:right;"> 4.6 </td>
   <td style="text-align:right;"> 3.1 </td>
   <td style="text-align:right;"> 1.5 </td>
   <td style="text-align:right;"> 0.2 </td>
   <td style="text-align:left;"> setosa </td>
  </tr>
  <tr>
   <td style="text-align:right;"> 5.0 </td>
   <td style="text-align:right;"> 3.6 </td>
   <td style="text-align:right;"> 1.4 </td>
   <td style="text-align:right;"> 0.2 </td>
   <td style="text-align:left;"> setosa </td>
  </tr>
