The styles of kable tables are controlled by CSS file. tbody can be used to change the colour of the content of the table, with thead able to change the header.

As shown by Lee S, you can create an external CSS file. However, you can also include the CSS directly within the R Markdown file, as markdown accepts raw HTML and passes it through unaltered. See here for some more details

Here is a full reproducible example:

---
output: html_document
---

# Test Project

<style>
   tbody tr:nth-child(odd){
    background-color: #F7FBFF;
  }
</style>


```{r}
knitr::kable(mtcars[1:5, 1:5])
```

enter image description here

This guide provides a good explanation of the table elements which can be controlled by CSS.

Download the RMD file http://www.reed.edu/data-at-reed/software/R/blogposts/tables_blogpost.Rmd

Change beginning of RMD file to this:

---
output: 
  html_document:
    keep_md: true
    css: mystyles.css
---

Create a css file called mystyles.css with following contents:

tbody tr:nth-child(odd){
  background-color: #F7FBFF;
}

Save to the same location as your RMD file.
